Frequently asked questions
What is the advantage of an internal hex plug over an external hex plug?
Internal hex plugs sit flush with the equipment face, eliminating external protrusions that could interfere with adjacent pipework, sliding fixtures or tight cabinet clearances.
Do these plugs require external sealing tape?
Tapered PT/R models come with pre-coated thread sealant, and parallel G-thread models include a captive elastomeric O-ring, enabling immediate leak-free installation without PTFE tape in most applications.
Are stainless steel 304 variants available?
Yes. The BP-S series in 304 stainless steel is maintained for chemical, food-grade or outdoor washdown applications.
