For whatever life brings.

Coyote Air-Lock

A lightweight, dual-suspension pin system designed to combine suction suspension comfort with pin suspension security. The airtight seal prevents air from coming into the bottom of the socket, creating suction and reducing pistoning even without a sleeve! For patients who struggle with pin engagement, use the Deep Air-Lock with the 11 click pin.

  • Suction allows for less traction on the limb for increased comfort and decreased liner wear

  • Expulsion valve or suspension sleeve are not needed to maintain suction in most cases

  • Water-resistant

  • Dual suspension, suction pin lock system

  • Gain extra suspension even without a sleeve

  • Reduces pistoning and traction on end of limb

  • Decreases distal pressure

  • Single-stage lamination

  • Offset alignment capablity

  • *Do not use with elevated vacuum

With the Air-Lock's unique dual suspension, it makes the prosthesis a part of you.

What Creates the Suction?

The pin attaching the liner firmly into the distal end of the airtight lock and socket holds the residual limb in place. From the pin holding stable at the bottom of the socket the only place for trapped air to go is out the top of the socket. As the fleshy part of the limb moves and takes up more space this creates pressure pushing more air out, creating negative pressure or suction in the lower part of the socket holding the limb more firmly in place over a larger area and helping to eliminate pistoning.

A one-way valve like the CQL Valve can be added if help is needed to release the air from the bottom of the socket

Which Pin to Choose?

The two-part pin has been our standard for years. The solid brass pin can be quieter and has a higher pull strength. The thread is determined by which liner you choose.
