Bonded Seals are also known as Dowty Seals or Dowty Bonded Washers.They are high pressure seals which are used in the Mechanical, Hydraulic and Pneumatic sectors.They comprise of a metal washer and an elastomeric ring which is bonded inside the diameter.The metal washer prevents over-compression and limits deformation of the elastomeric ring.

BS/A self-centering combination sealing gaskets are suitable for metric, imperial, BSP threaded pipe joints and screw plugs. No special processing of the sealing groove position is required. It is an ideal accessory for fast and automatic installation. The operating temperature is -30℃~100℃, and the working pressure shall not exceed 39.2MPa. Non-automatic centering combination gaskets are suitable for pipeline systems with oil as the medium, for welding, ferrules, expansion pipe joints, screw plugs and pressure system sealing of mechanical devices. To prevent leakage of oil, fuel, water and medicines, the nominal pressure is up to 40MPa and the working temperature is -25℃~+100℃.

PTFE Stainless Steel Oil Seals offer a robust sealing solution with an inner wall featuring grooves that create an inward thrust, enhancing the seal's retention. Made with a top-grade PTFE material, these seals are ideal for oil-free operations, providing immediate low-friction performance post-restart. The use of high-strength, wear-resistant hardware ensures long-term durability without rust. An integrated oil return line in the design boosts sealing performance. Suitable for a variety of applications including compressors, motors, and food processing equipment, these seals are a reliable choice for harsh environments.

Perfluoroether rubber is a preferred sealing material for high-end manufacturing and extreme working conditions. Its high performance makes it perform well in demanding applications. FFKM has excellent temperature adaptability (-10℃ to 320℃) and unparalleled chemical resistance. It also has excellent resistance to gas and liquid permeation, weather resistance, ozone resistance, and self-extinguishing properties, ensuring safety and reliability under extreme conditions. Its high density and good mechanical properties further enhance the sealing effect and are suitable for scenes with explosive decompression, CIP, SIP and FDA requirements.
