Description

This cupseal made for those who find difficult to dissasemble the threadlocked piston heads and those who prefer cup type sealing instead of O ring type.
This new type of cup has an O ring like contact surface around it’s edge, instead of a flat rubber set in an angle to fit inside the cylinder. This let the piston head seal without increased friction in the cylinder regardless it’s tolerances.
The airbrake is integrated into the cup, made of the same flexible rubber, it flexible and bends to fit in the nozzle just right.
The suggested lubricant is thin silicone oil or dry ptfe. Since it’s stored without lubricant it may takes a few shots to get the right sealing and performance, expanding the edges outside with lubricant (like with the original Silverback cup seal) helps the process.
