Danfoss (Weatherhead)

Steel Pipe Seal-Nut for Male Pipe Threads

Material: All Danfoss “Seal-Nuts” are precision machined from 12L14 steel; insert is made of molded virgin Teflon®. 
Pressure: Up to 3000 psi operating pressure.  
Temperature Range: Designed to operate satisfactorily from -100°F to +500°F. 
Makes every pipe connection leakproof. Permits positioning of pipe elbows and tees full 360° without overtightening Thread seal-nut on pipe thread. Tighten pipe elbows and tees to proper position, then tighten seal nut for positive seal. • Eliminates leaks on all pipe threads — Dry Seal or standard. No pipe compound required. Quick, easy installations in cramped quarters where wrench clearance is limited. • “Seal-Nuts” are an economical substitute for straight thread O-ring boss fittings using original female pipe ports. “Seal-Nuts” give you positive seal on directional fittings like tees and elbows without distorting mounting bosses or damaging expensive valves and pumps.
