Tube OD x 3\/8 in. Female NPT Connector (4FSC6N-316) – Lot of 5\u003c\/h3\u003e\n\u003cp\u003eThe Parker A-LOK 4FSC6N-316 Female NPT Connector is a high-precision, instrument-grade compression fitting engineered for secure, leak-tight connections between fractional tubing and male NPT threaded pipe in critical analytical, chemical, and bioprocessing fluid systems. Built around Parker's proven two-ferrule A-LOK design, this fitting utilizes a precision-machined front ferrule for gas-tight sealing and a geometry-controlled back ferrule for superior mechanical grip without stressing the tubing wall. Constructed from corrosion-resistant 316 stainless steel, the 4FSC6N connector connects a 1\/4 inch outer diameter (OD) tube to a 3\/8 inch female NPT thread. Supplied as a lot of 5 fittings, this hardware package provides high-reliability fluid containment under extreme pressure, vibration, and thermal cycling conditions.\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance \u0026amp; Structural Attributes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTwo-Ferrule A-LOK Mechanical Grip: Features a dual-ferrule system that distributes gripping force evenly, providing vibration-resistant hold and zero-leak sealing capability up to the full working pressure rating of the tubing.\u003c\/li\u003e\n\u003cli\u003e316 Stainless Steel Construction: Provides high tensile strength and superior corrosion resistance against aggressive chemical media, solvents, and environmental exposure.\u003c\/li\u003e\n\u003cli\u003eSilver-Plated Nut Threads: Internal nut threads are silver-plated to eliminate thread galling and ensure consistent makeup torque during assembly and remake.\u003c\/li\u003e\n\u003cli\u003ePrecision NPT Thread Profile: Machined with clean, burr-free 3\/8\" Female NPT threads for reliable sealing when paired with PTFE tape or thread sealant.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCatalog \/ Part Number: 4FSC6N-316\u003c\/li\u003e\n\u003cli\u003ePrimary Manufacturer: Parker Hannifin Corporation (Instrumentation Products Division)\u003c\/li\u003e\n\u003cli\u003eProduct Series: A-LOK Series Compression Tube Fittings\u003c\/li\u003e\n\u003cli\u003eFitting Style: Female NPT Tube Connector (Tube to Female Pipe)\u003c\/li\u003e\n\u003cli\u003eConnection Port 1 (Tube Side): 1\/4 in.
