Products Description
This series of universal rubber gaskets are made of mainstream general rubber materials such as NBR, EPDM and natural rubber, produced by integral molding and precision sheet cutting technology. The finished products feature uniform thickness, smooth surface, no burrs, no bubbles and stable overall elasticity. Full sets of standardized specifications cover various outer diameters, inner diameters and thicknesses, which can match most general equipment, pipeline flanges, valve end covers and fastener compression positions on the market without special customization. The materials have excellent weather resistance, water resistance, weak oil resistance and aging resistance under conventional working conditions, and will not harden, crack or deform after long-term static compression. With good flexibility and fitting performance, the gaskets can automatically compensate for slight assembly tolerances and tiny unevenness of equipment planes to block micro gaps effectively. Featuring tool-free installation and strong interchangeability, they are suitable for mass standardized supporting and scattered equipment maintenance replacement, serving as basic rubber and plastic accessories for universal sealing scenarios in all industries.
Product Advantages
Full-scenario universal compatibility
Adopting industry-standard dimensional systems, it is compatible with most civil, light industrial and general industrial equipment and pipeline sealing positions. It is not limited to a single industry or equipment, far more versatile than special customized gaskets, and realizes one-stop supporting for multiple sealing scenarios.
Flexible fitting for reliable micro-sealing
With excellent rubber elasticity, it deforms evenly under pressure and closely fits all kinds of flat docking surfaces. It effectively fills tiny assembly gaps and scratch gaps, accurately solving micro-leakage of water, gas and oil as well as dust intrusion under conventional working conditions with stable sealing performance.
Weather and aging resistance for stable service life
Optimized formulas for indoor and semi-outdoor conventional working conditions deliver excellent oxidation resistance, aging resistance and dry-wet alternation resistance. It is not easy to yellow, harden or crack during long-term use, maintaining stable static sealing performance and reducing replacement frequency.
Multi-functional buffering and protection
In addition to basic sealing performance, it buffers assembly extrusion force, avoids metal rigid contact and equipment surface wear, and realizes shock absorption, noise reduction and anti-loosening effects, integrating sealing, protection and stabilization functions.
High cost performance and easy maintenance
Mass-produced with sufficient spot stocks and low comprehensive cost. It features simple installation and replacement without subsequent maintenance, which is very suitable for complete machine supporting, bulk engineering procurement and daily equipment maintenance replacement.

Product Q&A
Q1：What is the difference between rubber gaskets of different materials and how to choose?
A: EPDM features excellent waterproof, weather and aging resistance, suitable for plumbing and outdoor equipment; NBR has superior oil resistance, ideal for engine oil, fuel and industrial oil circuit scenarios; food-grade silicone is non-toxic, odorless and high-temperature resistant, perfect for drinking water equipment and kitchen appliances. You can choose according to the working medium and environment.
Q2：Are universal rubber gaskets high-temperature resistant and leak-proof?
A:Processed with strict vulcanization technology, the ordinary version can withstand high temperatures up to 120℃, and the special version up to 200℃. It will not soften, deform, harden or crack under high temperature. With stable rebound and sealing performance, it can maintain long-term leak-proof effect after correct installation.
Q3：Are universal rubber gaskets prone to falling off after installation? What is their service life?
A:With moderate hardness and tight fitting, the gasket is not easy to loosen or fall off after compression fixation, adapting to vibration and alternating dry and wet working conditions. Under normal room temperature conditions, its service life is 3-5 years; under outdoor, high-temperature or corrosive conditions, it can work stably for 1-3 years, far better than ordinary low-quality rubber gaskets.
