Square O-rings - Square Cut Washer Rings

Square-rings are square cross-section seals designed to be interchangeable with standard AS568 O-Rings. Complete interchangeability within standard glands is assured in most applications.

Description - EPDM (Ethylene Propylene)

EPDM is a copolymer of ethylene and propylene. Ethylene propylene diene monomer (EPDM) is produced using a third monomer and is particularly useful when sealing phosphate-ester hydraulic fluids and in brake systems that use fluids having a glycol base. Heat resistance-Up to 300°F (149°C) (max. 400°F (204°C) in water and/or steam).
