SMS Sanitary blue EPDM Gasket for Union

1. Brief Introduction of Products:

A union gasket in sanitary fittings is a specialized elastomeric or plastic seal used within a threaded union assembly. It sits between the male ferrule (part) and the flat-faced liner (weld part), compressing to create a flush, crevice-free seal when tightened by the union nut. 

2. These gaskets are critical for maintaining hygiene in industries like dairy, brewing, and pharmaceuticals. Key Characteristics:

• Design: Unlike the standard flanged Tri-Clamp gaskets, union gaskets are designed to fit into a grooved recess specifically machined into the male part of the union fitting. 

• Materials: They are strictly manufactured from food-grade and hygienic materials such as EPDM, Silicone, PTFE (Teflon), Viton (FKM), or NBR.

• Compliance: Because they handle consumable products, they typically carry regulatory approvals like FDA, USP Class VI, and NSF 51 standards.
