Advanced Couplings – Gaskets & O-Rings

Advanced Couplings gaskets are manufactured for use in the Food & Dairy, Chemical and Pharmaceutical industries where standard tube/pipe couplings are required. All Advanced Couplings gaskets are FDA approved and are supplied as Type 2 Lipped as standard, aiding the ease of assembly. Advanced Couplings stock a full range of gasket sizes and materials to suit all the popular standards including : BS4825-3, DIN32676, ISO1127, SMS 3017 and Schedule sizes.

About the Gaskets

Elastomer Gaskets – EPDM, Silicone & VITON®

All Advanced Couplings’ Elastomer gaskets are designed and manufactured to give a smooth transition throughout the bore when fully assembled. To guarantee this degree of control all Advanced Couplings’ Elastomer gaskets are produced to have a shore hardness of 75/85 IRHD. Gaskets are produced from compounds that conform to FDA code of regulations for rubber and rubber-like materials: Title 21, paragraph 177.2660. They also meet Class1 material classification of the 3A sanitary standards USDA and standard 51 of the NSF. The Elastomer range of gaskets are colour coded to aid identification: EPDM =Black/Blue; VITON®=Green; Silicone =White/Clear.

PTFE Solid (Teflon®)

The Advanced Couplings range of PTFE Solid gaskets are manufactured by machining from solid billets of virgin PTFE with a hardness of 60/65 shore D, guaranteeing precision components coupled with low porosity properties. Gaskets are produced from compounds that conform to FDA code of regulations for TEFLON® and Fluorocarbon resin materials : Title 21, paragraph 177.1550 for use in contact with foodstuffs. The gaskets also meet Class1 material classification of the 3A sanitary standards. The manufacturing process lends itself to offering solid gaskets in special sizes to suit all customers requirements and most requests for non-standard components can be accommodated.

PTFE Envelope (Teflon®)

Envelope gaskets are of a composite construction being a PTFE (TEFLON®) outer, with a VITON® filler as standard. The design offers a seal which has a degree of elasticity giving good sealing properties coupled with flexibility. The PTFE (TEFLON®) element of the gasket is produced to have a hardness of 60/65 shore D, and is manufactured from a solid billet of virgin PTFE (TEFLON®). The gasket is designed to minimise the effects of stress cracking in the product contact area, thus adding aseptic qualities to the sealing system. Envelope gaskets are produced solely from compounds that conform to FDA code of regulations for TEFLON® and Fluorocarbon resin materials : Title 21, paragraph 177.1550 for use in contact with foodstuffs, the gaskets also meet Class1 material classification of the 3A sanitary standards. The manufacturing process lends itself to offering solid gaskets in special sizes to suit all customers requirements and most requests for non-standard components and variations on filler materials can also be accommodated.
