Engineered for ease of use, this connector nipple is straightforward to install using standard plumbing tools. Its robust stainless steel construction not only enhances system reliability but also maintains a clean, professional appearance in exposed installations.

What is the difference between the BSP and NPT versions of this adapter?

The BSP version has 1/2 BSP female to 1/2 BSP male threads with an outside diameter of about 20.9 mm, while the NPT version has 1/2 NPT female to 1/2 NPT male threads with an outside diameter of about 21.3 mm. BSP and NPT are not interchangeable, so you must match the adapter type to your existing plumbing.

How do I choose the correct thread type for my installation?

Check the specifications of your existing fittings or consult your plumber. In many regions, BSP is standard, while in North America, NPT is more common. The adapter must match the thread standard (BSP or NPT) of both your supply pipe and your fixture.

Can I use thread seal tape or pipe dope with this adapter?

Yes. For a watertight connection, apply appropriate thread seal tape (PTFE/Teflon tape) or pipe thread sealant compatible with your plumbing standard, following local plumbing codes and best practices.

Can I cut or shorten the adapter if the length is too long?

No. The adapter is a finished stainless steel fitting with threaded ends; cutting or modifying it may damage the threads, compromise sealing, and void any warranty. Instead, select the closest length option that meets your needs.

Does the listed length include the threaded portions, or is it the body length only?

The stated length refers to the overall extension length of the fitting. For precise installation planning, you should also consider the engagement depth of the male and female threads in your specific fixtures.
