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.

- For Use With: Air, Hydraulic Fluid, Natural Gas, Oil, Steam, Water
- Temperature Range: -100° to 450° F
- Specifications Met: ASTM A574, ASME B1.20.3
- Pipe Nipples and Pipe: Use Schedule XXH steel
- Flanges: Use Class 1500 steel
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.
