LOCTITE SI 5331, Liquid Thread Sealant for Pipes, Silicone Sealer for Cold and Hot Water Carrying Plastic and Metal Pipes, Vibration Resistant Silicone Sealant, 12x100ml

Product Information

Type of pipe sealant: 3 main types of pipe sealants include PTFE, anaerobic, or pipe joint compounds – each suitable for different types of applications. It depends on the product. Soft-set sealants, for example, never dry completely and are thus better at withstanding vibration or changes in pressure. Q: How do you apply pipe thread sealant? For taper/parallel threads – ensure you position the adhesive where the threads will engage fully. Gaps and cure times may be greater than expected with this joint configuration.

Pipe dope is a versatile compound but usually comes in cans of at least 4 ounces. That’s just too much for most tool boxes. Rectorseal 25790 comes in a convenient tube to always be close at hand. However, threads can be prone to wear. One cause might be expansion and contraction, a cycle that happens when pipes freeze and thaw. Threads might wear from pressure changes or when subjected to vibration. Any of these conditions can cause a leak. In a water pipe, that could mean flood damage running into thousands of dollars. A leak in a gas pipe has potentially lethal consequences. However, these sealing resins require the presence of metal ions to cure, so they normally do not work on plastic pipe threads. They also can take up to 24 hours to seal properly. Anaerobic resins are a step up in price over pipe dope, making them the most expensive option. In general, resin products work best for specialist applications, rather than for general-purpose use around the home and yard. Anaerobic resin compounds use a different cure chemistry than solvent-based pipe dopes and do not contain solvents. The cure begins when the sealant is confined within the threads of the metal pipe connection and air is excluded.Typical applications for MH052 pipe sealant include sealing oxygen pipelines in hospitals, breathing apparatus, aircraft oxygen systems and more. MH052 is also suitable for other gases and liquids and has excellent chemical resistance.

Strictly speaking, Teflon tape is not a thread sealant (Fig. 1). The tape may have the effect of clogging the thread path, but it does not actually adhere to surfaces as a true sealant should. During installation, the tape must be carefully wrapped in the direction of the threads or it unravels and tears.

PTFE tape seems like a basic product, yet it’s surprisingly resilient. General-purpose tape, which is white in color, can frequently hold up to temperatures ranging from minus 212 degrees to 500 degrees Fahrenheit. Tapes used for gas, which are yellow, have a similar upper limit, but some can handle cold to minus 450 degrees. Permabond MH052 has BAM approval for use with gaseous oxygen up to 10 bar (145 psi) and 60°C (140°F). Standard anaerobic sealants are unstable in oxygen-rich systems. The instability could cause fire or explosions. MH052 is a unique formulation which is stable in oxygen rich environments providing a safe means to seal threaded joints in gaseous oxygen systems up to 10 bar (145 psi) and 60°C (140°F).
