Loctite 55 Pipe Sealing Cord(roll)

LOCTITE® 55 Pipe Sealing Cord is a general-purpose, non-hardening thread sealant designed for sealing metal and plastic pipe threads and fittings. Unlike conventional liquid pipe sealants or PTFE tape, Loctite 55 pipe sealing cord is wound directly from its dispensing package onto the pipe threads, delivering an immediate, full-pressure seal with no cure time required. This makes Loctite 55 pipe sealing cord particularly valuable in situations where a system needs to be pressure-tested or put into service right after assembly. Tapemart, a trusted Loctite distributor, stocks genuine Loctite 55 pipe sealing cord for plumbing, gas line, HVAC, and industrial piping professionals who need a fast, reliable, and reusable sealing solution.

Key Features and Benefits

•      Non-hardening cord format provides an instant, full-pressure seal with zero cure time

•      Allows joints to be readjusted after tightening — up to 45–90° depending on application — without breaking the seal

•      Suitable for both metal and plastic tapered pipe threads, including fittings up to 4 inch NPT

•      Approved for use with natural gas, potable water, and compressed air applications

•      Certified to EN 751-2, DVGW, WRC, BGA KTW, and NSF/ANSI Standard 61, with Australian Gas Association approval in relevant markets

•      Rated for working temperatures from -10°C to 150°C and working pressures up to 2000 kPa in approved applications

•      Clean, tape-free application that avoids the shredding and thread damage sometimes associated with PTFE tape

Typical Applications

Loctite 55 pipe sealing cord is widely used for sealing threaded joints on metal and plastic pipework carrying gas, potable water, compressed air, and other industrial fluids. It is a preferred choice in plumbing and HVAC installations, gas distribution systems, manifold and coupling assemblies, and general industrial piping where technicians need to make a joint, test it immediately, and adjust the fitting angle if required without waiting for a sealant to cure. Because it carries potable water and gas certifications in multiple regions, Loctite 55 pipe sealing cord is also a strong fit for regulated plumbing and utility work.

How to Use Loctite 55 Pipe Sealing Cord

Unwind the appropriate length of Loctite 55 pipe sealing cord from the dispenser based on the pipe diameter, then wrap it around the male thread in the direction of tightening, ensuring even coverage across the engaged thread length. Assemble and tighten the fitting as normal; the cord will compress and seal immediately under pressure, without needing time to set or cure. Avoid over-applying the cord, since excess material can be pushed out during assembly and make the joint mechanically harder to tighten fully. If repositioning is needed, Loctite 55 allows the joint to be adjusted within the rotation range specified on the technical data sheet without compromising the seal. Store the product in a dry location between 8°C and 21°C for optimal performance, and consult the official Loctite 55 technical data sheet for cord length recommendations by pipe diameter.
