1. EPDM rubber O-rings from us are manufactured with a special composition intended for pipework ensuring a robust and waterproof sealing.
2. The food-grade EPDM O rings we offer comply with the FDA standards for food-contact materials; the material used is highly pure and resistant to the migration of substances that could be harmful to the contact medium.
3. Besides providing the standard sealing solutions, we also make molds for manufacturing seals of particular colors, sizes, and shapes. These service offerings can be used for both industrial and residential piping systems.
Small leaks that last for days or weeks or months can cause a huge waste of water and increase the cost of maintenance in the long run. Many contractors have experienced that sealing rings, which are very tight when they first get installed, quickly become hard, crack, and lose their flexibility after only one summer or winter season.
Our EPDM rubber O-rings are able to solve the above problems as they keep very good elasticity for a long time. They are made from high-quality new EPDM rubber with a very small amount of reclaimed rubber, so they stay very resilient over the temperature range from -40°C to 120°C. They are still flexible and resistant to cracks, thus capable of providing a good seal even when they are subjected to very hot or very cold environments.
Introduction to Metric EPDM O rings:
These O-rings, accurately molded from top-grade EPDM, find application in a variety of pipework systems such as water supply and drainage, HVAC, chemical processing, and city infrastructure. Besides excellent resistance to weather, water, and aging, they provide very good sealing performance, which makes them a multi-purpose, high-functionality sealing option for pipeline flanges, joints, valves, and fittings.

Compatible Media for EPDM O rings:
Inferior seals tend to have too many fillers and less rubber to reduce the price, which makes the end products harden and crack easily. On the other hand, our products use only virgin EPDM rubber and the Mooney viscosity is very carefully controlled to give a stable performance.
They can be used with tap water, rainwater, sewage, hot water, cooling water, steam, and even with weak acid or alkaline solutions. On the other hand, they are not intended for use with mineral oils or fuels.
Core Advantages of EPDM Rubber O Rings:
1. Water-resistant acids, alkalis, and temperatures at the same time make it possible to minimize the risks of failures even when subjected to hot and cold changes.
EPDM is custom-made for water environments; when properly formulated according to the FDA, it can also meet food contact material standards. Usually, its temperature suitability spans from -40℃ to 120℃, so the material will not change its properties in the coldest frozen or hottest water pipes. Even if the conditions keep changing from hot to cold, the rubber keeps its wonderful elasticity and bounce back features.
2. Long-lasting sealing elasticity, resistant to compression deformation, effectively preventing leaks.
EPDM rubber o ring tends to have a very good spring-back property, with a permanent set (under 100℃×22h) held at ≤30%. Its excellent compressibility and adaptability enable it to effectively seal even minute gaps in pipe flanges, valves, joints, and other parts, therefore, preventing the leaking of water, air, or fluids, as well as assisting the pipeline systems in minimizing the risk of leakage in both dynamic and static sealing conditions.
3. Complete standard specifications, ample stock, supporting custom orders.
We mainly support three major standards: GB (China), ANSI (US), and JIS (Japan). At the same time, we are able to make non-standard and special-shaped seals according to the drawings or samples. Our purpose is to satisfy the varying requirements of industrial and residential pipeline projects.
Practical Applications of EPDM O Rings for Plumbing:
Our EPDM o-ring for plumbing can be used for sealing and connecting a wide range of individual pipeline systems such as municipal water supply and drainage pipelines, HVAC water pipes, fire protection pipelines, chemical fluid pipelines, underfloor heating pipes, water pumps and valves, pipe flanges and joints, hydraulic equipment, and central air conditioning pipelines.
