Product Description

Coin Splined Seal is a bonded sealing washer consisting of a metal retainer combined with a precision-molded rubber sealing element. The elastomer seal is mechanically and chemically bonded to the metal retainer to provide reliable sealing against internal and external pressure.

Roman Seal proprietary bonding technology helps prevent seal separation and improves durability in demanding aerospace and hydraulic sealing applications.

These sealing washers are designed to replace or provide an equivalent solution to Parker STAT-O-SEAL products used in hydraulic fittings and threaded fastener sealing applications.
