PVC BSP Male Threaded Nipple Fittings — Reliable Pressure-Rated Connections for Water Supply Plumbing
When a leaking joint or an incompatible fitting stalls a plumbing project, the root cause is almost always a mismatch in thread standard or material. These PVC BSP male threaded nipple fittings are engineered for DIYers, plumbers, and irrigation installers who need a dimensionally accurate, pressure-rated connector that threads cleanly into BSP female sockets without binding or cross-threading.
Each fitting is moulded from Polyvinyl Chloride (PVC) and features a BSP (British Standard Pipe) male thread on both ends. Available in six pipe sizes — 20 mm (1/2"), 25 mm (3/4"), 32 mm (1"), 40 mm (1-1/4"), 50 mm (1-1/2"), and 63 mm (2") — with a bright white finish. Wall thickness and pressure rating vary by diameter; see variant options for exact figures.
Typical applications include cold-water supply lines in residential and light-commercial buildings, drip and sprinkler irrigation manifolds where a corrosion-free nipple is needed between PVC pipe runs, and garden water-feature plumbing where a lightweight yet rigid male-threaded PVC nipple pipe fitting simplifies assembly without specialist tools.

Compatibility: Designed for BSP (British Standard Pipe) female-threaded sockets and valves. Not compatible with NPT (National Pipe Thread) fittings. Always verify thread standard before ordering.
✅ Key Features of These PVC BSP Male Threaded Nipple Fittings
-
🔩BSP Male Thread Both Ends
Precision-formed BSP threads on both ends ensure a consistent, leak-resistant engagement with standard BSP female sockets, valves, and couplings.
-
🛡️Corrosion-Free PVC Construction
Polyvinyl Chloride resists rust, scale, and most household chemicals, making these fittings suitable for cold-water plumbing where metal nipples would corrode over time.
-
📐Six Sizes: 20 mm – 63 mm
Covers the most common residential and light-commercial pipe diameters from 1/2" to 2", reducing the need to stock multiple fitting types across different projects.
-
⚖️Lightweight for Easy Handling
PVC's low density means these nipples add negligible weight to overhead or wall-mounted pipework, simplifying single-person installation in tight spaces.
-
🌿Suitable for Irrigation Systems
The smooth internal bore minimises flow restriction, making these fittings a practical choice for drip lines, sprinkler manifolds, and garden water-feature plumbing.
-
📦Flexible Pack Quantities
Available in packs of 1 to 30 pieces per order, so you can buy exactly what a single repair needs or stock up for a full installation run.

❓ Frequently Asked Questions
What pipe sizes do these PVC nipple fittings cover?
Six sizes are available: 20 mm (1/2"), 25 mm (3/4"), 32 mm (1"), 40 mm (1-1/4"), 50 mm (1-1/2"), and 63 mm (2"). Select the size that matches your existing pipe's outer diameter and thread specification.
Are these fittings compatible with NPT-threaded pipes and valves?
No. These fittings use BSP (British Standard Pipe) threads, which have a different pitch and taper profile from NPT (National Pipe Thread). Mixing the two standards will result in cross-threading and leaks. Always confirm your existing fittings are BSP before ordering.
Can I use these fittings for hot-water lines?
Standard PVC is rated for cold-water applications and is typically suitable up to around 60 °C (140 °F). For hot-water or steam lines, CPVC or brass fittings are the appropriate choice. If you are unsure about your system's operating temperature, contact us to confirm suitability.
How do I prevent leaks when installing these threaded nipples?
Apply PTFE (plumber's) tape to the male threads before assembly — wrap 2–3 layers clockwise when viewed from the thread end. Hand-tighten first, then use a strap wrench (not metal pipe grips, which can crack PVC) to snug the fitting. Avoid over-tightening, as PVC threads can strip under excessive torque.
Are these fittings suitable for irrigation and outdoor use?
Yes. PVC is inherently corrosion-resistant and performs well in outdoor irrigation systems, garden water features, and sprinkler manifolds. For buried or UV-exposed installations, consider wrapping exposed sections or using UV-stabilised pipe to complement the fittings.
What is the pressure rating of these PVC nipple fittings?
Pressure ratings vary by pipe diameter and wall thickness. Larger diameters typically carry a lower pressure rating than smaller ones at the same wall thickness. Please refer to the variant options or contact us for the specific pressure rating of the size you need.
How do I choose the right pack quantity?
For a single repair or connection point, the 1 PCS option is the most economical. For a full irrigation manifold or multi-outlet installation, packs of 10–30 pieces offer a lower per-unit cost. Count the number of connection points in your project before selecting a quantity to avoid unnecessary surplus.
