Product Description

The Bonded Neoprene Sealing Washer is a type of sealing fastening component and accessory that is permanently bonded together as a single unit by the high-temperature vulcanization process between Neoprene and metal flat gaskets, and cannot be disassembled. The rubber part provides elastic sealing, while the metal part restricts compression and enhances structural strength. This is an integrated sealing gasket specially designed for preventing leakage and loosening at bolt, threaded, and pipeline connection points.

Advantages

The inside part of the Bonded Neoprene Sealing Washer that does the sealing is made of neoprene rubber, and the outside or back part is metal. This two‑in‑one design gives it some advantages that regular washers or separate rubber seals just don't have:

(1) It seals well

When you tighten Bonded Neoprene Sealing Washer down, the neoprene layer stops water, oil, air, and refrigerants from leaking out.

(2) It won't get crushed too much

The metal outer ring limits how much the rubber can be squeezed. That keeps the rubber from getting flattened too far and losing its stretch, so the seal lasts a long time.

(3) It handles vibration

The rubber's flexibility soaks up vibration from the equipment. Even on rough or uneven surfaces, it stays tight and doesn't come loose easily.

（4）Adapt to rough surfaces

Butyl rubber can automatically fill in the tiny depressions or scratches on the surfaces of the connected parts, thereby reducing the requirements for processing accuracy.

（5）Resistant to high temperatures

The Bonded Neoprene Sealing Washer can operate stably within the temperature range of -30°C to +120°C and has certain aging resistance and oil resistance properties.

（6）Easy installation

There is no need to separately install metal washers and rubber sealing rings. One part can fulfill both functions, reducing assembly time.

（7）Various application scenarios

Widely used in bathroom fixtures, automotive fuel and water pipe connections, air conditioning refrigeration pipelines, outdoor electrical enclosures, hydraulic and pneumatic connectors, etc.
