4″ End Cap (Pressure PVC-U)

Seal a large pressure line with confidence. The 4″ End Cap (Pressure) is designed for 4″ PVC-U pressure pipework, giving you a permanent solvent weld stop end in pump-fed systems .

When you’re working with high-flow bottom drains, drum filters or large return lines, this is the fitting that safely closes the run.

Why it’s a dependable choice

• Made for 4″ pressure PVC-U pipe
• Solvent weld socket for a strong, watertight seal
• Suitable for pump-fed pressure systems
• Matches the wider 4″ pressure fittings range

Where it fits in your system

Typical uses include:

• Capping a 4″ bottom drain line during staged builds
• Sealing a manifold branch on a gravity-to-pump conversion
• Closing a pressure return for future expansion

Always use pressure-rated fittings on pump-fed lines. Waste fittings are not built for the same operating pressure.

Installation notes

• Clean pipe and fitting with PVC pipe cleaner before gluing
• Apply suitable solvent cement for pressure PVC-U
• Push fully home with a slight twist and hold briefly
• Allow full curing time before restarting the pump

Work in a well-ventilated area and follow adhesive instructions carefully.
