PVC UPVC Pipe End Caps — Reliable Plain-End Pipe Termination for Water Supply Systems

When a pipe run needs a clean, leak-free termination, a poorly fitted cap can mean costly water damage or a failed pressure test. Whether you are a plumber finishing a domestic water supply line, a landscaper capping off an irrigation branch, or a DIYer sealing a drainage stub, these PVC UPVC plain end caps give you a secure, tool-free push-fit closure that holds firm under normal working pressure.

Each cap is moulded from rigid UPVC (unplasticised polyvinyl chloride) with a thick wall construction for added strength. The plain socket bore accepts standard OD pipe in sizes from 20 mm (approx. 0.79 in) up to 110 mm (approx. 4.33 in), covering the most common residential and light-commercial pipe diameters. Wall thickness and exact bore tolerance vary by size — see variant options for specifics.

Typical applications include capping unused tee or cross outlets on cold water supply manifolds, terminating irrigation sub-mains during staged installation, sealing drainage inspection stubs, and blanking off redundant pipe ends during pressure testing of new plumbing systems.

🔗 Compatible with standard OD UPVC pressure pipe to BS EN 1452 / AS/NZS 1477 and equivalent schedules. Confirm pipe OD before ordering.

✅ Key Features of These PVC UPVC Plain End Caps

  • 🔒Secure plain-socket fit — smooth bore accepts standard OD pipe for a snug, solvent-weld-ready termination that resists pull-out under pressure.
  • 🏗️Thick-wall moulding — reinforced wall construction resists cracking under mechanical stress and maintains shape across the full size range from 20 mm to 110 mm.
  • 💧Water-supply rated UPVC — rigid, non-toxic UPVC material is suitable for cold potable water, irrigation, and drainage applications.
  • 🌡️Corrosion and chemical resistance — UPVC does not rust, scale, or degrade in contact with chlorinated water, mild acids, or common soil chemicals.
  • 📐Wide size matrix — nine diameters (20 / 25 / 32 / 40 / 50 / 63 / 75 / 90 / 110 mm) and six quantity options (1–10 pcs) let you order exactly what the job requires.
  • ⚙️Solvent-cement compatible — plain socket bore is ready for standard UPVC solvent cement bonding for a permanent, pressure-rated joint.

❓ Frequently Asked Questions

How do I choose the right cap size for my pipe?

Match the cap size to the outside diameter (OD) of your pipe, not the nominal bore. For example, a 20 mm cap fits pipe with a 20 mm OD. Check your pipe markings or measure with calipers before ordering. If you are unsure, contact us to confirm compatibility.

Can these end caps be used for hot water systems?

These caps are moulded from rigid UPVC, which is rated for cold water supply and drainage applications. UPVC is generally not recommended for continuous hot water above approximately 60 °C (140 °F). For hot water systems, consider CPVC or PP-R fittings instead.

Do I need solvent cement to install these caps?

For a permanent, pressure-rated joint, yes — apply a compatible UPVC solvent cement to both the pipe end and the socket bore, then push the cap firmly onto the pipe and hold for 30 seconds. For temporary blanking during pressure testing, a dry push-fit may hold short-term, but solvent bonding is recommended for final installation.

Are these caps resistant to corrosion and outdoor UV exposure?

UPVC is inherently resistant to rust, scale, and most common chemicals including chlorinated water and mild acids. For prolonged outdoor UV exposure, painting the fitting or using UV-stabilised pipe wrap is advisable, as standard UPVC can become brittle over many years of direct sunlight.

What is the pressure rating of these end caps?

Pressure rating varies by size and wall thickness. As a general guide, smaller diameter UPVC fittings typically handle higher working pressures (often 10–16 bar for 20–50 mm sizes) while larger diameters are rated lower. Please contact us or refer to the product datasheet for the specific size you need.

Can I use these caps for drainage and waste pipe systems?

Yes. These plain end caps are suitable for capping drainage and waste pipe stubs where the pipe OD matches the cap size. They are commonly used to blank off inspection openings or unused branch outlets during construction. Confirm the pipe OD matches the cap bore before ordering.

How many pieces should I order for my project?

We offer 1, 2, 3, 4, 5, and 10-piece options so you can order exactly what you need. For single repairs or one-off terminations, the 1 Pcs option is ideal. For larger installations or to keep spares on hand, the 5 Pcs or 10 Pcs packs offer better value per piece.
