PVC Pipe Interface Seal

PVC pipe interface seals are important components that connect different parts in the PVC pipe system (such as pipe fittings, valves, joints, etc.). Their main function is to prevent liquid or gas leakage at the connection point and ensure the overall sealing and stability of the pipe system. The seal is made of high-quality elastic materials, such as EPDM rubber, EPDM, silicone, etc., with good flexibility, elasticity and chemical stability, and is suitable for long-term use under various environmental conditions.

• Scope of application

PVC pipe interface seals are widely used in many fields, including but not limited to:
Building drainage system: used for drainage pipe connection of residential, commercial and public buildings to ensure the sealing and anti-leakage performance of the drainage system.
Industrial pipeline system: suitable for chemical, electric power, metallurgical and other industrial fields, connecting various PVC pipes to prevent medium leakage.
Municipal water supply system: used for the connection of urban water supply pipe networks to ensure the stability and safety of the water supply system.
Agricultural irrigation system: used to connect PVC pipes in irrigation projects to prevent water leakage and improve irrigation efficiency.
Temporary closure and testing: used to temporarily close the pipeline during pipeline installation, maintenance or testing to prevent pollution or leakage.

• Product features or advantages

High-quality materials: Made of high-quality EPDM rubber, EPDM or silicone, it has excellent corrosion resistance, aging resistance and chemical stability, and is suitable for a variety of chemical media and extreme environments.
Reasonable structural design: The seal is specially designed to fit tightly to the pipe interface, forming an effective sealing barrier to prevent the penetration of liquids or gases.
Easy installation: The seal is designed for easy installation, usually only manual pressure or wrench fixation is required, saving installation time and labor costs.
Strong weather resistance: It can withstand ultraviolet rays, extreme temperatures and various chemicals in water and wastewater systems to ensure long-term performance.
Compliance with industry standards: The product complies with relevant national standards such as GB/T 21873 "Rubber seals for water, drainage pipes and sewage pipes Interface seals Material specifications" to ensure its reliability and performance.

• Functional features

Leak-free connection: Through the compression and fitting of elastic sealing materials, a tight sealing structure is formed to effectively prevent the leakage of liquids or gases.
Strong adaptability: Suitable for PVC pipe interfaces of different sizes and types, including right-angle joints, T-joints, elbow joints, etc., to meet a variety of installation requirements.
Good pressure resistance: Able to withstand high working pressure, suitable for pressure-bearing pipe systems, such as siphon rainwater drainage systems, etc.
Environmentally friendly and safe: Adopting non-toxic and harmless materials, it meets environmental protection requirements and is suitable for scenes with high water quality requirements such as drinking water and food processing.
Easy to maintain: The seal has a simple structure, which is easy to inspect and replace, ensuring the long-term stable operation of the pipeline system.

• Technical features

High-pressure combined seal design: The combined design of the main seal ring, the first O-shaped seal ring and the second O-shaped seal ring significantly improves the sealing effect, which is suitable for pipe connections under high-pressure environments.
Structural optimization: The main seal ring adopts an integrated structure, with a rectangular cross-section at the bottom and an inverted trapezoidal cross-section at the top. After being pressurized, it fits tightly to the sealed part to enhance the sealing performance.
Low tightening torque: The design adopts low tightening torque to extend the service life of the seal and reduce the risk of damage during installation.
Multi-material compatibility: The seals are suitable for a variety of pipe materials, including PVC, UPVC, CPVC, etc., ensuring wide applicability.
Complete certification: The products are certified by international certification agencies such as NSF, DVGW, SVGW, WRAS, etc., ensuring their compliance in different countries and regions.
