Ultra-Advanced Product Features of RUBBER-KU Square Rubber Rings

1. Square Cross-Section Design for Superior Sealing Performance

One of the most important features of RUBBER-KU square rubber rings is the precision-engineered square or rectangular cross-sectional profile.

Unlike traditional round O-rings that create narrow sealing contact points, square rubber rings provide:
