Python Double Duty Overview
No more makeshift tools
The first true clamp, even better now
Gone are the days of hand exercises you can’t master, fussing with padding, not having the right size starting girth, using cable clamps not designed for PE work, trying to maintain erections or poor erection quality, and above all…the frustration of not gaining because you couldn’t figure out how to make clamping work.


Quality components
Made in the USA. Constructed of heavy duty machined components and medical grade parts, the device is designed for long term PE career use. The modular design can be repaired and upgraded as well, providing more value for your money.
Skin safe silicone
Unlike the cheap toys you may find online made from toxic chemicals, all components are made from the same type of silicone featured in Hollywood special effects makeup.
Simple
The device is designed for ease of use, with a focus on new PE users. Operation is one handed, universal, with a single knob to control pressure. Built strong for repeatable sessions.
Smooth Seal
No hard points to pinch your skin like cable clamps or press on delicate nerves.
99%
Of men fit in the Python
Accommodating circumferences from 3.5 in / 8.89 cm to 7.5 in / 19.05 cm.

Pressure stages
For both new and advanced users.

Clamp and hanger in one device. Benefit form the Airlock® technology and use up to 10 lbs / 4.53 kg of hanging weight.

The device can be used by itself as a standalone clamp, in concert with other Air-Lock clamps (units can be stacked), with your hands, or with a vacuum penis pump to provide amazing internal pressure every session.

Traditional vacuum penis pumps deliver slow progress by themselves and often require high vacuum pressures that can cause injury to see results. The Air-Lock Python increases internal pressure during your pumping sessions while lowering the required vacuum pressure to see results, keeping you safer while increasing session effectiveness. Lower operating vacuum pressure means greatly reduced chances for blisters.

2 pressure stages for both new and advanced users. Stage 1 is designed for those new to PE work, providing ample compression power while also yielding when pressure limits reach higher levels reserved for advanced users. Stage 2 provides a grip strong enough to impress even veterans of the PE community. Combined with a traditional penis air pump, the clamp can deliver amazing levels of clamping force.

Forget hand exercises or cable clamps to break down and weaken tissues before your length stretching sessions. The Python squeezes tight from the start to create micro-tears more effectively for the most effective stretching sessions.
Shockloader
I just received your air clamp and it's amazing. I am able to create way stronger internal pressure and my expansion is far better than with the cable clamp. The ease of use is amazing so when I'm in a hurry and can only bang out an hour, I know it's a worthwhile hour; I'm not sitting messing around with a wrap and trying to properly adjust the clamp, then taking it off after a set, to fumble around getting it back on and blah blah blah. I'm very grateful you made this thing...!
Clamp operation instructions
WARNING: Any numbness, tingling, excess coldness, or color changes to blue/black should not be ignored and are signs to release air pressure and remove the device as soon as possible. Restore circulation before continuing to use the product.
Step 1
Make sure the knob is set to the OFF (left, counter-clockwise position) and all air has left the device.
Step 2
Be partly or fully soft/flaccid to insert into the clamp. You can use soapy water to aid with lubrication for insertion. Using lotions may cause slippage during operation.
Step 3
If uncircumcised (uncut), be sure the foreskin is covering the head (glans) and insert it into the opening. The head will pop out of the foreskin on the other side of the clamp opening. If circumcised, use two fingers to compress and pull the head through the clamp opening.
Step 4
Slide the device all the way down to the shaft base, resting at the bottom.
Step 5
Gently turn the knob to the ON (right, clockwise position) to close the air valve. Do not overtighten the knob as it can damage the air valve.
Step 6
If using a vacuum pump, place the included pump cylinder seal on top of the clamp and center it on the clamp. Next, place the pump cylinder on top of the clamp seal, and make sure the clamp, seal, and cylinder are centered with each other.
Step 7
Slightly pump the clamp's air bulb to form a seal at the base.
Step 8
Become erect by use of stimulation or pump (set to 5 Hg). Full erect for shockloading, or approximately 80% erect (still floppy) for clamped squeezes or overall expansion work.
Step 9
Gently squeeze the clamp's air bulb to increase pressure until a surface tension on the penis is felt, becoming a slightly uncomfortable expansion sensation as the penis chambers are pushed to their expansion limits. Do NOT continue to add pressure if a stretched expansion feeling is felt at lower pressure levels.
NEVER pump to maximum pressure! If a bubble begins to form in the white sleeve, the device is beyond its limit and can fail (pop) if pressure is increased further..!!! Release some air to lower air pressure to safer levels.
Step 10
Set a timer (5 minutes maximum) and hold in you preferred sitting/standing position, slightly increasing clamp pressure as required to maintain the desired expanded sensation. Typical adjustment to pressure setting is every 1-2 minutes. Do not adjust unless pressure loss is felt. Any tingling, numbness, coldness, or change in color to blue and/or black should not be ignored and is a sign to release air pressure on the device and remove if needed.
Step 11
At the 5-minute mark, turn the clamp knob to the off (left) position and pressure should immediately drop.
Step 12
Leave the device on your penis. If using a pump, remove the cylinder and leave the clamp on. Massage the shaft and head to restore color and circulation.
Step 13
Repeat the setup procedure above, cycling between exercise and rest for up to 1 hour on a session day.
Step 14
To remove the device, be flaccid as possible. Apply soapy water around the shaft to slide the device off. Remember to wash your device to avoid bacteria growth and avoid urinary tract infections.
Shockloading
Clamping sessions are suggested to be done for 1-2 sets of 5 minutes each before wearing a length device to shockload the tissues.
Girth sessions
Done every other day to help preserve erection quality. Increasing workout duration past 1 hour of 5 minute sets or continued daily use without rest days can negatively impact erection quality.
Hanger operation instructions
WARNING: Any numbness, tingling, excess coldness, or color changes to blue/black should not be ignored and are signs to release air pressure and remove the device as soon as possible. Restore circulation before continuing to use the product.
Step 1
Make sure the knob is set to the OFF (left, counter-clockwise position) and all air has left the device.
Step 2
Be partly or fully soft/flaccid to insert into the clamp. You can use soapy water to aid with lubrication for insertion. Using lotions may cause slippage during operation.
Step 3
If uncircumcised (uncut), be sure the foreskin is covering the head (glans) and insert it into the opening. The head will pop out of the foreskin on the other side of the clamp opening. If circumcised, use two fingers to compress and pull the head through the clamp opening. Soapy water can be used to lubricate the device opening for easier insertion. Remember to dry off the water before step 4.
Step 4
Slide the device all the way down to the shaft base, resting at the bottom.
Step 5
Gently turn the knob to the ON (right, clockwise position) to close the air valve. Do not overtighten the knob as it can damage the air valve.
Step 6
Slightly pump the clamp's air bulb to form a seal around the shaft. Observe for leakage or misalignment.
Step 7
Pump the air bulb until a solid grip pressure is felt on the shaft. No pain should be felt. NEVER pump to maximum pressure!
Step 8
Gently apply tension to test grip strength before adding any weight or letting it hang by itself from the shaft.
Step 9
Carefully lower the weight, testing the grip strength as its lowered. Be aware of your feet and other objects beneath the weight and protect as needed. Load the device one pound at a time if you are just starting out. The device is meant for long hours of wear, so avoid the temptation to use more than 4-6 lbs. The best use is just enough force to feel soreness at the base while wearing. Loading more weight does not speed up results and can potentially cause injury.
Step 10
Do not adjust device air pressure unless pressure loss or slippage is felt. If you begin to get erect while wearing, release the air pressure and let it pass and focus on the erection subsiding. Do not get fully erect in the device if possible. If sitting, hang the device over the edge of the chair to keep constant tension.
Step 11
Be on constant watch for any signs of pain, tingling, numbness, excess cold, or color changes to blue/black. Should you sense any of these signs, release air pressure and remove the device immediately to restore circulation. As you become familiar with the device, releasing just the air pressure will work to restore circulation. If sitting, hang the device over the edge of the chair to keep constant tension. The device works best while standing/walking when worn under clothing.
Step 12
To remove, use soapy water around the opening and shaft for lubrication. Wash device before re-use with mild dish washing liquid, no hard chemicals that may damage silicone. Remember to wash your device to avoid bacteria growth and avoid urinary tract infections.
