Mill-rose 70989 Ptfe Thread Seal Tape 520in X 0.5in 10000 Psi

Product Description

The MILL-ROSE 70989 is a medium-density PTFE thread seal tape designed for sealing threaded pipe connections in plumbing, HVAC, and mechanical systems. The tape measures 520 inches long by 0.5 inches wide and 0.0025 inches thick, providing consistent coverage on standard 1/2-inch pipe threads. It is rated to 10000 psi, making it suitable for both low-pressure domestic water lines and higher-pressure gas or hydraulic applications. Plumbers, pipefitters, and HVAC technicians use this tape to prevent leaks at threaded joints on metal and plastic fittings. Domestic manufacture ensures consistent material quality and density throughout the roll.

This tape is used on threaded connections in residential and light commercial plumbing, natural gas lines, compressed air systems, and hydronic heating systems. The medium-density formulation provides enough body to fill thread voids without tearing during application on standard NPT fittings. It is a routine consumable in service truck inventory for any trade professional working with threaded pipe assemblies.

Key Features

• Rated to 10000 psi for use across a wide range of pressure applications
• Medium-density PTFE construction resists tearing during thread wrapping
• 520-inch length delivers extended use per roll on high-volume jobs
• 0.5-inch width fits standard NPT and pipe thread profiles
• 0.0025-inch thickness provides consistent sealing without over-packing threads
• Domestically produced for uniform density and material consistency

Compatibility

Designed as an OEM-style replacement consumable for use on standard NPT threaded pipe fittings in plumbing, HVAC, gas, and compressed air systems.

Installation Notes

Thread seal tape is applied by plumbers and pipefitters as part of routine threaded joint assembly. Shut off and depressurize the line before disassembling any existing joint. Wrap the tape clockwise around male threads, typically two to three passes, so the tape tightens rather than unravels when the fitting is turned in. Do not use thread seal tape as a substitute for pipe dope on connections requiring an anaerobic sealant, and always verify local code compliance for the specific fluid or gas being conveyed.
