Swagelok SS-8-CP 316 Stainless Steel Pipe Cap, 1/2 in. Female NPT

Close off a line the right way and stop worrying about it. The Swagelok SS-8-CP pipe cap threads onto any 1/2 in. male NPT end and seals it with 316 stainless steel strength. You reach for this cap when you plug a spare port, cap a future tie-in, or isolate a section for hydro test. The female NPT threads bite clean and hold pressure, so your dead-end stays leak tight through thermal cycles and vibration. Refineries, chemical plants, and instrumentation panels use these caps by the hundreds because they end a run cleanly and pass inspection every time. The 316 stainless body fights corrosion in wet, salty, and chemical service where carbon steel rusts out. This is a finished-pattern pipe fitting, forged and machined to Swagelok tolerances, so it mates with your existing NPT hardware without fuss. Need other sizes, a pipe plug, or the matching hex nipple? Call Collins-Oliver, your authorized DK-LOK distributor in Baton Rouge, and we will fill out the run. Order the caps you need and seal your system with confidence.
