Extreme-Pressure Steel Threaded Pipe Fittings
The strongest steel fittings we offer, these can withstand extreme-pressure applications. PTFE-coated steel fittings have better corrosion resistance than galvanized and zinc-plated steel fittings.
Plugs with a 7/8" taper sit flush to the surface for a low profile.
NPTF (Dryseal) threads are compatible with NPT threads.
