Flat Cross-Section Rings with Rubber Sealing Rings and Smooth Machined-Looking Edges

Elastomer compound selection and flash removal quality together determine the sealing performance of flat cross-section rubber sealing rings; EPDM handles steam and weather cycling while FKM (Viton) suits chemical and fuel contact, and flash at the parting line raises the ring above the groove seating plane and prevents full compression of the sealing face. Prisaisi (Shenzhen, Guangdong, mould factory established 2021, Shajing Bao'an District) moulds these flat cross-section rubber sealing rings with smooth moulded edges at their in excess of 4,000 m² Shenzhen facility, with ring ID, OD, cross-section height, and parting line quality confirmed against your released print during in-process inspection. IATF 16949 and ISO 9001 certifications cover automotive, energy storage, and electrical power transmission rubber sealing rings applications. Key industries: drones. Include ID/OD dimensions, cross-section height, hardness specification, and elastomer grade in your RFQ package. For a moulding project quote from our shenzhen team.
