Decoding the part number: \"4F\" = 1\/4 in female NPT (FNPT) connections on both inlet and outlet; \"C4L\" = check valve, 4 (1\/4 in) port size, low-cracking-pressure poppet design; \"1\" = 1 psig nominal cracking pressure; \"SS\" = 316 stainless steel body and internals. The poppet-style mechanism provides bubble-tight shutoff with low cracking pressure, making it suitable for gas and liquid instrumentation service including process analyzers, sampling systems, and instrument tubing manifolds where backflow prevention and corrosion resistance are required. The FNPT × FNPT end connections accept standard 1\/4 in NPT male fittings on both ends, and the compact hex-body design allows inline installation with a wrench. Country of origin is USA per box label.\u003c\/p\u003e\n\u003ch3 style=\"margin-top:24px;margin-bottom:12px;font-size:16px;color:#56555b;border-bottom:2px solid
