Key Features of UPVC Rubber Ring Gasket for Water
-
Excellent elastic seal: uses EPDM material that conforms tightly to the pipe outer wall under compression for reliable sealing.
-
Aging resistance: the EPDM resists ozone and UV, remaining flexible without hardening or cracking over long-term use.
-
Easy installation: is pre-installed socket groove during production, so no additional sealant is required on site.
-
Precise dimensions: manufactured to standard tolerances, each delivers optimal fit with UPVC fittings and pipes.
Manufacturing Process of UPVC Rubber Ring Gasket for Water
Each is made by compression or injection molding. The EPDM compound is vulcanized and formed with precise control of cross-sectional shape and dimensions to match the socket groove.
Critical Process Parameters of UPVC Rubber Ring Gasket for Water
Every is checked against these parameters:
-
Control of compound formulation and the vulcanization process to meet physical properties required by.
-
Precise control of cross-section dimensions and inner diameter tolerance of the gasket.
-
Testing of hardness, tensile strength, and compression set of the EPDM material.
Raw Material Characteristics of UPVC Rubber Ring Gasket for Water
-
Material Composition: Ethylene Propylene Diene Monomer (EPDM), compliant with potable water standards.
-
Material Properties: The EPDM body offers excellent ozone and aging resistance, good elasticity and compression recovery, and a wide operating temperature range from -30°C to +80°C, complying with potable water hygiene standards.
Typical Applications of UPVC Rubber Ring Gasket for Water
-
Sealing for UPVC rubber ring joint fittings: provides the flexible seal between pipe spigot and fitting socket.
-
Flexible joint sealing in water supply piping systems: absorbs minor pipe movement and ground settlement.
-
Pipe connections requiring quick installation: the pre-installed lets joints go in fast without solvent cement.
Application Scenarios of UPVC Rubber Ring Gasket for Water
-
Sealing for all UPVC rubber ring joint fittings — is the standard sealing element across the full fitting range.
