Threaded Plugs & Caps
Plastic caps and plugs are intended to keep dust and debris out of hoses and other plumbing parts during storage (and minimize leakage from used parts). Aluminum or steel caps and plugs should be used whenever pressure is to be contained. Equivalent AN numbers are given for reference where applicable. These fittings conform to JIC and SAE specifications.
Note: AN and BSP nomenclature can be confusing because the nominal sizes do not refer to the outside diameter of the threads. If you are not sure if you have AN or BSP threads, check in our Threaded Fitting Guide.

These AN Plastic Flare Caps are threaded and not the push-on type, and are preferred for their added security.
