When an open pipe end is left exposed during installation, renovation, or system modification, debris, pests, and moisture can enter and compromise the entire line. Plumbers, contractors, and hands-on DIYers working with drain, waste, or irrigation systems need a dependable way to seal off unused pipe ends cleanly and permanently. These PVC cap end caps deliver a secure, adhesive-bonded blanking solution that holds up in both wet and dry environments.
Each cap is molded from Polyvinyl Chloride (PVC), offering a rigid yet lightweight body with consistent wall thickness. The inside diameter ranges from 20mm (~0.79 in) up to 200mm (~7.87 in), covering the most common metric pipe sizes used in residential and commercial plumbing. The grey finish matches standard PVC drainage pipe, giving installations a clean, uniform appearance.
These PVC pipe end caps are well suited for sealing off branch tees during phased construction, capping unused drain outlets in bathroom or kitchen rough-ins, and blanking irrigation laterals during off-season storage. Their smooth interior bore accepts solvent cement for a permanent, watertight bond on PVC drain pipe blanking applications.
Available in 12 inside diameter sizes from 20mm to 200mm, covering the full spectrum of common metric PVC drain and pressure pipe.
Smooth interior socket accepts standard PVC solvent cement for a permanent, watertight seal on drain pipe blanking and capping tasks.
PVC material resists moisture, rust, and common household chemicals, making these caps suitable for both indoor and outdoor plumbing applications.
The PVC construction keeps each cap light for easy handling while maintaining the structural rigidity needed to hold pressure in sealed pipe systems.
The standard grey color matches most metric PVC drainage pipe, ensuring a tidy, professional-looking finish on exposed or visible pipe ends.
Choose from 1 to 20 pieces per order to match your project scope — whether you need a single replacement cap or a bulk supply for a full installation.

Match the cap's inside diameter (ID) to the outside diameter (OD) of your pipe. For standard metric PVC drainage pipe, the pipe's nominal size typically equals its outside diameter — for example, a DN50 pipe has a 50mm OD and requires a 50mm ID cap. If you are unsure, measure the pipe OD with calipers and select the matching cap size from the variant options above.
When bonded with a compatible PVC solvent cement, these caps form a rigid, permanent joint suitable for low-to-medium pressure drainage and vent applications. They are designed for drain, waste, and vent (DWV) systems rather than high-pressure water supply lines. For pressure-rated applications, verify the working pressure rating of your specific pipe system before use.
Yes. PVC is inherently resistant to moisture, rust, and a wide range of household chemicals including mild acids and alkalis commonly found in drain water. These caps will not corrode, rot, or degrade in typical indoor plumbing or outdoor irrigation environments. For exposure to aggressive chemicals or UV sunlight over extended periods, consider additional protective measures.
Use a standard PVC solvent cement (also called PVC glue or PVC primer + cement) rated for drainage or pressure pipe, depending on your application. Clean and dry both the pipe end and the cap socket before applying cement. Follow the cement manufacturer's cure time instructions before pressurizing or using the system. Solvent cement is not included with the caps.
These caps are designed specifically for metric PVC pipe. They are not directly compatible with ABS, CPVC, or metal pipes without the use of an appropriate transition adapter. PVC solvent cement will not bond to ABS or metal surfaces. If you need to cap an ABS pipe, use an ABS-rated cap or a rubber push-fit end cap instead.
Select the packing quantity that matches your project needs. For a single repair or replacement, 1 Pcs is sufficient. For rough-in work where multiple branch outlets need to be temporarily or permanently capped, ordering 5, 10, or 20 Pcs at once reduces per-unit cost and ensures you have spares on hand. Bulk packs are ideal for contractors working on multi-outlet drain installations.
PVC is widely used in underground drainage and outdoor irrigation systems due to its resistance to soil moisture and common ground chemicals. These caps can be used in buried or outdoor applications when properly bonded with solvent cement. For prolonged direct UV exposure above ground, note that grey PVC may become slightly brittle over many years; wrapping or painting exposed sections can extend service life.
