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.

Pipeline Fluid Blockers
Also known as paddle blinds, these fit between two flanges to temporarily block the flow while you work downstream.
304 stainless steel blinds are more corrosion resistant than steel blinds.
