Description

Product Overview
The slimline sealing washer is a specialized sealing solution designed for the axial application of air-conditioning fittings, serving as a replacement for radially clamped O-rings in standard air-conditioning fittings. This product features a metal ring with an elastomer ring of trapezoidal cross-section that is bonded and vulcanized inside.

Material and Construction
The slimline ring consists of a metal insert made from carbon steel (cold-rolled and cold-worked strip), aluminum, or stainless steel, and is protected by an anti-corrosion treatment (Zn-Ni). The elastomer component is available in EPDM and HNBR compositions, with a violet EPDM blend offering optimized chemical resistance to R1234yf and approval by major automotive OEMs such as BMW, Daimler, and General Motors.

Features
  • Compatible with R134a and R123yf fluids
  • Material certified by leading automotive OEMs
  • Metal insert options: carbon steel (cold-rolled and cold-worked strip), aluminum, or stainless steel
  • Anti-corrosion treatment: Zn-Ni
  • Axial application
  • Standard dimension list (generic dimensions for air-conditioning fittings)

Benefits
  • Chemical resistance
  • Very low permeability
  • Reduced costs, as no groove machining is required
  • Easy assembly and installation
  • Distinguish between two identical-looking joints (Poka-Yoke)

Markets and Expertise
  • Automotive
  • Industry
  • Off-road
