Frequently Asked Questions
What thread types are available for these square head plugs?
We offer both BSP (British Standard Pipe) and NPT (National Pipe Thread) versions to suit various marine piping standards. Please specify your thread standard and size when ordering.
Are these brass plugs suitable for seawater applications?
Yes, the marine-grade brass alloy used provides excellent corrosion resistance in seawater environments. For extended service life, optional tinning or chrome plating can be specified.
What is the maximum working pressure of these plugs?
The pressure rating varies with size and thread type, but typical ratings are up to 3000 psi for smaller sizes. Always check the individual size specification for exact ratings.
How should I install a square head plug?
Simply wrap the threads with a suitable sealant tape or compound and tighten with a wrench on the square head. Ensure the thread engagement is sufficient for a leak-tight seal without over-torquing.
