I have a question about gasket material

Guide To PTFE Gasket Material

A Guide To PTFE An in-depth look at PTFE, and the gasket materials that are made from this versatile fluorocarbon polymer. On this page: Opperating Temperature | Why use PTFE | Dielectric PTFE | PTFE Fillers | PTFE Properties | PTFE Chemical Resistance | RAM’s PTFE Materials Available | Price Fluctuations PTFE (Polytetrafluoroethylene) is a […]

Gasket Materials By Industry

Commonly Used Gasket Materials By Sector: Oil and Gas Generally this industry will utilise spiral wounds, ring type joints, Kammprofile gaskets, non-asbestos material including brand names Klinger and Flexitallic (previously called Novus). Composite materials including mica and graphite, all these materials are utilised in high temperature, high pressure environments. Automotive This industry will generally utilise silicone as a high temperature polymer that can be supplied in O-ring, sheet and liquid form. Nitrile and viton that are […]

Why use a thin gasket?

Thinner is better – for sheet gasket materials We recommend using the thinnest possible gasket in most instances. The reasons for this are; Less leakage – smaller cross section of gasket material exposed to the internal pressure Resistance to Blow-out due to the smaller cross-sectional area Stronger compression strength contributes to higher surface loads able […]

Gasket Storage, Shelf and Service Life

Rubber has a shelf life, most of our materials used for gaskets have some rubber component. The shelf life refers to the time the gasket is still usable for service. So, if the rubber is nearing the end of its shelf life, it is still considered suitable for service use. If it has exceeded its […]

Gasket Traceability and Certification

Many gaskets require conformance for their application. RAM can provide conformance for any parts – just ask or tell us what conformance you require. Conformance can be supplied as part of the material type or the manufacture of the goods. Common types of conformance are; Potable Water (WRAS) approval. UL – UL is predominantly a […]

What is a Gasket made of?

Gasket’s are usually made from a flat and flexible sealing material. There are many types of material for different applications. Common materials include cork, rubber, non-asbestos fibre, graphite, silicone, paper, PTFE, shim and many more. For high temperature and high pressure some gaskets are made entirely of metal such as RTJ (ring type joints) and […]

Chemical Compatibility & Resistance

Gasket Material Chemical Compatibility & Resistance Choosing the correct gasket material for your application is critical, especially in an environment where you may be sealing against aggressive chemicals, such as strong acids or alkalis. In this situation you will want to know which chemicals are present; and make sure that you are using a gasket […]

Gasket Materials Guide

What follows is general guide to gasket materials: their properties and applications. Let’s first of all divide gasket materials into a few broad categories: (Note 1 bar = 14 p.s.i or 100,000 newtons/sq. Metre) 1. Low pressures (less than a bar) a) Temperatures below 100 centigrade (212 farenheit) Simple lid or dust seals can utilise […]
