EPDM Rubber Tri clover Gaskets
EPDM Tri clover Seals are a very popular Hygienic Fitting due to providing a smooth, non-contaminating internal pipework joint.
They are part of a Union that consists of two ferrules which are compressed together using a clamp and a gasket between the two ferrules which provides a tight seal. Tri clamp Seals are manufactured from EPDM and are easy to remove by hand using the single hinge clamp wing nut.
EPDM General Properties
Being non-polar elastomers EPDM offers a good performance in polar fluids such as alcohols, hydrogen sulfide (H2S), super-critical carbondioxide, water, steam, ketones etc., but perform badly in non-polar fluids such as hydrocarbon oils, lubricants and greases.
Note: Standard EPDM Ring Type Joint O’Ring Temperature rating for EPDM “E” gasket material is -51Â°C to 148Â°C.
