PVC Nipple Bsp Male Threaded Pressure Fittings Pipe Fitting ID 20mm~63mm

A BSP male threaded nipple is a short fitting with external (male) BSP threads on one or both ends. It screws directly into any BSP female-threaded port — such as a valve body, pump inlet, pressure gauge, or female coupling — to create a secure, pressure-rated threaded joint. Wrap the threads with PTFE tape before assembly to ensure a leak-free seal.

Match the BSP size to the female thread on your valve or fitting. The variant names show both the metric ID and the BSP inch equivalent: 20mm = ½″ BSP, 25mm = ¾″ BSP, 32mm = 1″ BSP, 40mm = 1¼″ BSP, 50mm = 1½″ BSP, 63mm = 2″ BSP. If unsure, check the markings on your existing valve or measure the female thread diameter with a thread gauge.

Color choice is typically based on your system's color-coding convention. White is common for general plumbing and potable cold-water lines. Blue is often used for potable water or irrigation systems. Grey is standard for UPVC pressure pipe systems. If your system has no color code, any color will perform identically — choose the one that matches your existing pipe or fittings for a consistent look.

No. Standard PVC is rated for cold-water service only, typically up to 60 °C (140 °F) under reduced pressure. For hot-water supply lines, use CPVC or brass fittings with the appropriate BSP thread. These nipples are designed for cold-water supply, irrigation, and pressure distribution applications.

Yes. PTFE (polytetrafluoroethylene) thread-seal tape is required to achieve a leak-free joint on BSP parallel threads. Wrap 2–3 layers of PTFE tape clockwise around the male threads before assembly. Do not over-tighten PVC fittings — hand-tight plus approximately one additional quarter-turn with a wrench is typically sufficient to compress the tape and seal the joint without cracking the fitting.

PVC threaded joints, when properly assembled with PTFE tape and not over-tightened, are reliable for typical cold-water working pressures found in residential and light-commercial systems. The pressure rating varies by size — see variant options for specifics. Avoid mechanical stress on the fitting after installation, as PVC threads can crack if subjected to side-loading or over-torquing.

Count the number of threaded connection points in your system that require this fitting, then select the pack quantity that matches or slightly exceeds that number. The 3-pack and 5-pack options offer a lower per-unit cost compared to ordering singles, making them a practical choice for manifold builds, irrigation systems, or any project with multiple connection points of the same size.
