First-Class Materials for Absolute Reliability Every single component is made of selected and particularly high-quality materials. The improved valve technology and geometry of the coupling allow to lubricate and grease the O-rings as required. In this way, the best functionality possible, strong resistance and long durability are guaranteed. Different materials (brass, stainless steel) Different connection types Ergonomic, non-slip sleeve shape Dripless valve Closed sleeve position when coupling and decoupling O-ring made of FKM Seals FKM: offers high-resistant seals made of FKM for dripless quick connect couplings. These are also installed in the plugs with male thread. Advantages: • Heat resistant up to 200°C (oil: 200°C, water: 150°C, air: 200°C) • Highly resistant against all common media • Significantly better gliding properties and minimum wear (low adhesive tendency) • High elasticity (no crack formation) according to DIN 53504 • High abrasion resistance of the O-ring • Significantly increased lifetimes of couplings High-Performance FKM For high-temperature applications we recommend to use a high-performance FKM sealing ring. • Extreme heat resistance up to 220°C continuous temperature (oil: 220°C, water: 180°C, air: 220°C) • High resistance against synthetic oils • Very good chemical resistance and high resistance against aliphatic hydrocarbons (fuels) • Steam/ hot water optimised For easy identification, the coupling sleeve is marked with a green anodized aluminium ring. Other special seals (e.g. EPDM, FFKM) on request. 267
