Products Description
This series of thin flat rubber washers adopts high-precision integral compression molding technology, with regular flat shape, uniform thickness, smooth flat end surface, no splicing, no burrs and no warping edges, achieving precise and controllable dimensional tolerance. Multiple high-quality materials including NBR, EPDM, food-grade silicone and polyurethane are optional, which can be flexibly matched according to different working requirements such as waterproof, oil-resistant, high-temperature resistant and anti-aging scenarios. With flexible texture and excellent resilience, the washers can evenly fit flat contact surfaces under pressure, fill tiny gaps, and effectively prevent water seepage, air leakage, loosening and abnormal noise. Treated with high-temperature vulcanization process, the products feature stable structure, no hardening, cracking, deformation or aging after long-term use, with outstanding compression resistance, wear resistance, waterproof and anti-corrosion performance. Suitable for narrow installation spaces without affecting equipment assembly accuracy, they are easy to install and highly universal, supporting mass production of standard specifications and customized processing of special sizes.
Customization Capability
Ultra-thin & Flat for Narrow Gaps
Adopting ultra-thin flat design with uniform and thin thickness, it is specially developed for narrow installation gaps and flat joint surfaces, solving the problems of unmountable thick ordinary washers, assembly protrusion and poor fitting, and maximizing the retention of equipment assembly accuracy.
Dual Functions of Sealing & Buffering
It integrates multiple functions including sealing, shock absorption, anti-slip, anti-loosening and insulation. It can effectively prevent water, oil and air leakage to eliminate hidden leakage risks, buffer equipment operation vibration, reduce abnormal noise caused by metal friction, and avoid loosening and falling off of screws and joints during long-term operation.
Stable & Anti-aging Material
Made of high-quality rubber raw materials and shaped by vulcanization process, it has good flexibility and strong compression resistance. It is not easy to age, crack or flatten and fail in long-term alternating dry-wet and slight vibration environments, with far better weather resistance and wear resistance than ordinary inferior flat washers and longer service life.
High Precision & Wide Compatibility
With flat end surface, burr-free design and precise size, the standardized specifications are compatible with most mainstream bathroom joints, home appliance accessories, hardware screws and instrument equipment interfaces. It is easy to install without complex tools and highly universal, capable of replacing various ordinary flat washers.
Customizable & Cost-effective
It supports non-standard customization of thickness, inner and outer diameter, color and material, accurately meeting the special working condition needs of various precision equipment. With stable batch supply, strict quality control and high qualification rate, it greatly reduces customers' procurement and replacement costs.
Product Applications
Thin flat rubber washers are suitable for all kinds of small gap, flat end face and precision assembly scenarios, covering civil and industrial fields. In civil fields, they are widely used for sealing and buffering of bathroom faucets, shower joints, pipe fittings, water heaters, water purifiers and small home appliances. In industrial fields, they apply to hardware fasteners, screw gaskets, instruments and meters, insulation and anti-slip of electronic control equipment, pneumatic and hydraulic accessories, small pump valve sealing, automation equipment, precision machinery assembly, small photovoltaic parts and electronic equipment vibration and noise reduction. Especially suitable for narrow gap scenarios where ordinary thick washers cannot be installed, it is the preferred accessory for precision assembly, flat sealing, vibration damping and anti-loosening scenarios.
Product Q&A
Q1：What is the difference between thin flat rubber washers and ordinary rubber washers?
A: The core difference lies in thickness and applicable scenarios. Thin flat washers are thinner with flatter end faces, specially designed for narrow installation gaps and flat butt joints. They will not protrude or compress equipment after installation and will not affect assembly accuracy. Ordinary washers are thicker and suitable for conventional large-gap scenarios. Thin flat washers are more suitable for fine sealing and vibration damping of precision equipment, small home appliances and flat end faces.
Q2：Is the waterproof effect good? Will it leak water?
A:It has excellent waterproof performance. The product has strong flat fitting performance, which can completely fit flat contact surfaces and fill tiny gaps after compression. Combined with the high resilience of high-quality rubber materials, it can achieve tight sealing, effectively preventing water seepage, dripping and leakage of water pipes, joints and home appliance interfaces, realizing zero leakage under correct installation and use.
Q3：How to choose different materials for thin flat rubber washers?
A:EPDM is suitable for plumbing, outdoor, waterproof and anti-aging scenarios; NBR has good oil resistance for oil circuits and mechanical lubrication equipment; food-grade silicone is non-toxic and odorless, suitable for water purification equipment and kitchen home appliances; polyurethane has stronger wear and compression resistance for high-frequency vibration and precision industrial equipment. You can select materials accurately according to service media and working conditions.
