• Oppose the piston with a spring and you’ve made a linear pressure gauge (P = kx/A).

• Push the piston a known distance and you’ve made a precision gas displacement device (V = Ax).

• Apply a precise pressure to the piston and you’ve made an actuator that pushes with a precise force (F = PA).

• Apply a precise vacuum pressure to the piston and you’ve made an actuator that pulls with a precise force (F = PA).

• Have us cut burr-free ports in the cylinder and you’ve made a valve.

• Bond a load to the piston and you’ve made a linear and/or rotary bearing.

• Come up with your own cool idea to make something useful!


Ultra-low friction graphite piston with precision bore borosilicate glass cylinder.

6 bore sizes from 5.6 mm to 44.4 mm.

Lengths as short as the length of the piston and as long as 1 meter. Stock lengths available.

    How are these products used?


    Dashpots and Shock Absorbers

    Airpot dashpots and snubbers are designed for low force damping and low energy dissipation to provide control of motion, force, and impact energy.

    Piston/Cylinder Sets

    Innovative designers use Airpot® piston/cylinder sets for many original and demanding applications. With their unparalleled low friction and response to forces as low as only a few grams and pressures less than 0.2 psi, our piston/cylinder sets are basic building blocks for any design involving pneumatic actuation, gas displacement, or even as a linear guide.
