|When you see how great these protective caps are, you'll wish you could put them on top of everything in your life to keep situations from getting messy. However, these threaded plastic caps and threaded plastic plugs are meant to be used for things like fittings and tube and nut assemblies. There are threaded plastic caps and plugs for flared JIC fittings, flareless tube and nut plastic threaded plugs, tapered caps and plugs and wide, thick flange plastic caps that can also be used as plugs. They protect against dirt and moisture.|
Though this is the plastic caps department, you'll also find products such as ASC Series threaded aluminum caps that form a low pressure seal on fittings and ASP Series 37 degree flared fitting threaded aluminum plugs that protect both 37 degree flared fittings and straight-threaded ports.
