Value Collection SS-TN-FT8 Compression Tube Nut 1/2 in

Product Description

The VALUE COLLECTION SS-TN-FT8 is a stainless steel compression tube nut designed to secure compression fittings in instrumentation and fluid-handling systems. Sized for 1/2-inch tube outside diameter with 1/2-inch female NPT end connections, this nut threads onto a compatible compression body to create a leak-tight mechanical seal around the tubing. At 0.69 inches in overall length, it is a compact, single-piece component. Material grade is 316 stainless steel, offering strong resistance to corrosion in aggressive media, high-purity, and high-pressure applications. Licensed plumbers, pipefitters, and instrumentation technicians are the typical installers of this hardware.

This compression tube nut is suited for use in process instrumentation lines, hydraulic tubing assemblies, pneumatic control systems, and industrial fluid distribution where stainless steel construction is specified. It pairs with standard compression fitting bodies that accept 1/2-inch OD tubing and NPT-threaded connections. Applications span oil and gas, chemical processing, food service, and HVAC instrumentation where corrosion resistance and dimensional consistency are required. The NPT thread standard ensures compatibility with widely used pipe fittings across North American trade installations.

Key Features

• 316 stainless steel construction provides corrosion resistance in demanding environments
• 1/2-inch tube OD sizing for use with standard half-inch compression fitting bodies
• Female NPT end connection follows the NPT and UNF thread standards
• Compact 0.69-inch overall length suits tight-clearance tubing runs
• Meets multiple ASTM and DIN EN material and dimensional standards
• Swagelok equivalent reference: SS-812-1

Compatibility

Designed as an OEM-style replacement compression tube nut for 1/2-inch OD tubing systems using NPT-threaded compression fitting bodies. Swagelok equivalent part number SS-812-1 is noted in the product data.

Installation Notes

Installation is typically performed by a licensed pipefitter or instrumentation technician. Depressurize and isolate the tubing line fully before disassembling or replacing any compression fitting component. Hand-tighten the nut onto the fitting body first, then advance with a wrench according to the fitting manufacturer's instructions for the specific ferrule type in use. Inspect tubing ends for squareness and burrs before assembly to ensure a proper seal.
