Product Name: NBR Quad Ring for Seal Used in Machines Model NO.: OEM Balance: Balanced Type: HU7 Standard: Standard Performance: Temperature Temperature: High Temperature Mechanical Seal Speed: General Speed Mechanical Seal Pressure: High Pressure Mechanical Seals Structure: Y Ring Color: Black, Red, Green Trademark: BRT Transport Package: 100 PCS Per Plastic Bags Specification: As customer's requirements Origin: Qingdao, China HS Code: 4016931000 Product Description Product:NBR Quad Ring for seal used in machines The Quad ring is suitable for static sealing but not dynamic sealing. The rectangular seal(quad ring) can be used for two way sealing fixed seals. The rubber seal is different, under the pressure state and the stress state, will slowly natural aging, and reduce elasticity. Therefore, the seal ring has a certain service life and is closely related to the quality of the sealing material. The quad seal ring has a relatively low aging rate due to its small amount of compression after installation. The rated pressure of O-ring is 32 MPa, while the Quad ring for seal used in machines is 50 MPa.Product Details:Materials: Nitrile rubber(NBR), Viton rubber(FKM), Silicone rubber, EPDM, Natural ruber. Other Names: Rubber seal, Rubber ring, X-ring, Quad seal, Quad seal ring.Hardness: Shore A 50 -85Operating temperature: -30 - 100 °CColor: Red, Green, Blue, White, Black,GreyApplication: The NBR Quad ring for seals are used in Machines, Automobile and other places which need static sealing.Product Features: 1.The NBR rubber performs excellent under low and high temperature.

The Quad ring is suitable for static sealing and the O ring is suitable for both static sealing and dynamic sealing. The rated pressure of O-ring is 32 MPa, while the Quad ring for seal used in machines is 50 MPa. The O ring is mainly used in hydraulic system and hydraulic parts. 2)What rubber do you use for the quad ring? There are many materials which can be used to manufacture the quad ring for seal. We usually choose different rubber according to different usage and requirements from the clients. The rubber are including Nitrile rubber, Viton rubber, Silicone rubber, Natural rubber,EPDM and etc.3) How about the package of your quad ring for seal used in machines? We pack the quad ring in plastic bags, usually 50 pcs or 100 pcs per bag. Then we put the bags to cartons.
