Oatey 31402D Water-Line Thread Seal Tape, 260 in L X 1/2 in W, 0.003 in T, PTFE Backing, Pink, -450 to 500 Deg F, 1/2-Inch x 260-Inch

Description

Product Overview

The Oatey 31402D Water‑Line Thread Seal Tape is engineered to provide a clean, positive seal on threaded connections across a broad range of industrial and scientific applications. Constructed with a high‑density PTFE backing, this pink tape measures 1/2‑inch in width and extends 260 inches in length, delivering ample coverage for large projects while maintaining a compact, easy‑to‑handle format. The 0.003‑inch (3‑mil) thickness offers a balance of flexibility and strength, allowing the tape to conform to irregular thread geometries without tearing or stretching excessively. With a tensile strength of 50 pounds, the tape can withstand significant mechanical stress, ensuring that the seal remains intact even under vibration or pressure fluctuations. The product is rated for extreme temperature conditions, performing reliably from –450 °F up to 500 °F, making it suitable for both cryogenic and high‑heat environments. Its water‑resistant formulation protects against moisture intrusion, reducing the risk of corrosion and leakage in plumbing, HVAC, and other fluid‑handling systems. The tape adheres directly to metal and plastic threads, eliminating the need for additional adhesives and simplifying installation procedures.

Usage

Designed for versatility, the Oatey 31402D seal tape excels in a variety of real‑world scenarios. In residential and commercial plumbing, it provides a reliable seal for copper, steel, and PVC pipe threads, preventing water leaks in supply lines, fixtures, and shut‑off valves. HVAC technicians rely on its temperature resilience to seal refrigerant line connections, where both low‑temperature expansion and high‑temperature compression cycles are common. In industrial settings, the tape is employed on pneumatic and hydraulic fittings, where high pressure and temperature differentials demand a seal that will not degrade over time. Its compatibility with both metal and plastic surfaces expands its utility to automotive brake lines, marine applications, and aerospace components that must meet stringent military specifications such as T‑27730A and UL 31 RO. The pink color aids visibility during installation, ensuring that technicians can quickly verify coverage and avoid missed spots. Because the tape is supplied on a convenient spool, it can be cut to length on‑site, reducing waste and allowing precise application to threaded lengths of any size.

FAQ

What types of threads can I use this tape on?

The tape is suitable for both metal and plastic threaded connections, including standard NPT, BSP, and metric threads commonly found in plumbing, HVAC, and industrial applications.

How does the temperature rating affect my application?

The tape’s rating of –450 °F to 500 °F means it will maintain its sealing properties in cryogenic environments as well as in high‑heat situations such as steam lines or hot‑water systems, eliminating the need for multiple sealants.

Is the pink color purely cosmetic?

The pink color enhances visibility during installation, helping technicians confirm complete coverage and avoid missed spots, which can be especially useful in low‑light or cramped work areas.

Can I use this tape on high‑pressure systems?

Yes. With a tensile strength of 50 lb and a proven track record in hydraulic and pneumatic applications, the tape can handle high‑pressure environments when applied correctly.
