The ASTM Standard UPVC End Cap is a heavy-duty, pressure-rated closure fitting engineered for permanent or temporary sealing at the termination of a UPVC pipeline. Its dome-shaped profile provides maximum resistance against line pressure shocks, making it ideal for system pressure testing, future expansion caps, or line dead-ends.
Technical & Design Advantages:
Pressure-Resistant Domed Design: Engineered with a thick, rounded head structure that efficiently distributes internal hydrostatic stress to prevent cap blowout.
Deep Solvent Socket: Deep socket depth ensures maximum bonding surface area when solvent welded, creating an airtight, leak-free seal.
Corrosion & Weather Proof: Immune to soil moisture, chemical degradation, and atmospheric weathering, suitable for buried or exposed installations.
Applications:
Pipeline dead-end capping in municipal and private water systems.
Pressure testing isolation ports during construction.
Agricultural irrigation line termination and flushing points.
Swimming pool and spa plumbing line capping.
