1 – BONDED SEALS Hutchinson offers two standard metal washer: - Rolled cold-worked mild steel with a tensile strength of 540 MPa protected by an anti-corrosion treatment - Cold-worked T316 stainless steel with a tensile strength of 540 MPa Other metals are listed in the table below with their specifications. The ring metal must be softer than the subassembly in which it is fitted. Special attention should be paid to combinations of metals that may form a bimetallic couple. The bonded seal consist of a metal washer of rectangular cross-section with a bonded and vulcanised inner rubber ring...

Bonded seals are offered in the catalogue in the 4 compounds below, in combination with a mild steel or T316 stainless steel metal insert. A selection of standard dimensions to meet the needs of industrial markets is available on page 148. This is an extract of our catalog, find the compound list in the full version by scanning this QR code.. If the maximum radial clearance cannot be respected, the seal must be centred on its outer diameter by using a counter-bore. To meet special requirements, our bonded seals can also be made with other compounds in our range (pages 41 to 43)....

The CETOPS seal is recommended for general applications and hydraulic and pneumatic transmissions in accordance with standard NF EN ISO 1179. D Banjo seals have been developed for systems using couplings for fluid transfer in cars and heavy goods vehicles. They offer significant advantages over copper or aluminium washers (without elastomer). The elasticity of rubber provides very reliable sealing and the self-centralising lip allows for easy fitting. For each thread diameter, two metal washers widths are offered, affecting the outer diameters A. Banjo fitting - Design and sizes based on...

Size standards BOLT - DC01 mild steel washers - Surface treatment: P18 now standard to replace P5 Application A large range of bonded seals is dedicated to the aerospace market and its regulations (EN 9100). Our bonded seals are manufactured according to international standards such as AGS, NSA, ASNA, etc. - Nominal sizes within the tolerance of AGS1186-13 (1958). Our tolerances follow this standard up to a certain threshold of technical feasibility. Exceptionally, our parts may be slightly outside AGS limits, without any foreseeable consequences on the application. The table below shows...

Specially designed for flange-fitting pipes, the PFS flange seal is made of a stainless-steel washer and a vulcanised elastomer lip. The slimline seal is a metal washer with a specially shaped vulcanised elastomer lip bonded to the inside. With its double lip, the PFS flange seal ensures permanent sealing, eliminates fugitive emissions and reduces downtime during maintenance operations. It is the ideal solution for all bolted flange fittings. Our purple EPDM offers optimised chemical resistance to R1234yf fluid and is certified by many OEMs such as BMW, Daimler and GM. Other EPDM or HNBR...

This is an extract of our catalog, find the full version here. Many environmental factors influence a seal’s sealing performance (fluids in contact, materials, manufacturing process, operating conditions, etc.). This extract contains recommendations that should be checked with our teams and that may change depending on the seal’s environment. These recommendations do not constitute a commitment on our part and all claims are excluded. It is essential to carry out final validation tests, which remain the customer’s responsibility. The information contained in this extract is valid at the...
