HPA O'Ring

Replacement Polyurethane O-ring for the neck of the HPA Cylinder, where the regulator sit on top of the HPA tank.

Polyurethane O-rings are made of general purpose polyurethane rubber, which is known for its combination of hardness and elasticity. Polyurethane O-rings have excellent abrasion resistance and high breaking strength. O-rings of polyurethane are resistant to oils, aging, ozone, heat, electricity, as well as to many chemicals.

Polyurethane O-rings perform well at low temperatures, but are not recommended for high temperature or superheated steam.

When installing your O-ring, and any time you remove then replace the regulator, we recommend us a good quality silicone grease to help the O-ring seat properly and seal properly.

(Please note, these come in a verity of colours which cannot be chosen, these are sold in pairs)
