Crosman 454 / Crosman 1600 Donut End Seal And O Ring Combo

I have made a re-seal kit out of NinjaTek TPU for the Crosman 454 and the Crosman 1600 vintage air pistols.

My o-rings and end seals are way tougher than traditional rubber o rings. Some benefits of NinjaFlex...

NinjaFlex TPU is made in the USA.

Shore Hardness = 85A

Truly flexible (no fill or layer manipulation required to achieve performance)

660% elongation allows for repeated movement and impact without wear or cracking

Polyurethane composition allows for excellent vibration reduction
