Value Collection SS-TN-FT12 Compression Tube Nut 3/4 in

Product Description

The VALUE COLLECTION SS-TN-FT12 is a stainless steel compression tube nut designed for use in high-integrity tubing systems where a secure, leak-resistant mechanical connection is required. Machined from 316 stainless steel to ASTM A276 and ASTM A479 material standards, this nut accepts 3/4 inch tube outside diameter and threads onto a 3/4 inch female NPT fitting end. At approximately 1.13 inches in overall length, it is sized for standard compression assembly in instrumentation, process, and fluid-handling applications. Installation requires no solder or brazing — the compression mechanism provides a reliable tube-to-fitting seal when properly torqued.

This compression tube nut is suited for residential and commercial plumbing, HVAC refrigerant line accessories, instrumentation tubing, and general industrial fluid systems where 316 stainless steel is specified for corrosion resistance. It is compatible with standard compression-style tube fittings accepting 3/4 inch OD tubing and 3/4 inch NPT threaded connections. Plumbers, pipefitters, and HVAC technicians working with stainless tubing assemblies will encounter this nut as a standard replacement or repair component.

Key Features

• 316 stainless steel construction meets ASTM A276, ASTM A479, and multiple DIN EN standards for material integrity
• 3/4 inch tube OD sizing pairs with standard compression ferrule sets
• FNPT end connection threads to 3/4 inch female NPT fittings per standard NPT and UNF thread specifications
• Overall length of 1.13 inches fits within typical compression assembly envelopes
• No soldering or welding required — mechanical compression connection
• Cross-references to Swagelok part number SS-1212-1

Compatibility

Designed as an OEM-style replacement compression tube nut for systems using 3/4 inch OD tubing with 3/4 inch FNPT end connections. Cross-references to Swagelok part number SS-1212-1 for direct substitution in compatible compression fitting assemblies.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or qualified HVAC technician. Depressurize and isolate the tubing system completely before disassembly or fitting replacement. Verify tube OD and thread engagement before applying torque — damaged or mismatched threads will compromise the compression seal. Follow applicable IPC and ASME B31 piping code requirements for the system being serviced.
