Eliminates Shredding and Customer Complaints

A leading Indian OEM of electrical switchgear manufactures used PTFE tapes to seal the drain valve and plug threaded joints in their single-phase and three-phase electrical distribution transformers. However they received field complaints of leakage, shredding of PTFE tape & clogging.

Maintains Seal under Pressure and after Slight Adjustments

An Indian manufacturer of domestic water purifiers used ptfe tapes to seal the plastic pipe thread joints. Though no leaks were detected at assembly / testing stage, the joints loosened during transportation & handling causing leak. PTFE tapes offeres lubricity that many times results in over tightening of the plastic joints – leasing to cracks and under vibrations – aids loosening. PTFE tapes also tend to shred and lose their sealing properties when the joints are re-adjusted.

Contractor Chose Loctite Sealants over PTFE Thread Tapes

Sayer Constructions was installing fire hydrants around building sites in Australia. They had previously used PTFE Thread Tapes to seal the treaded pipe joints in the hydrants. However, thread tapes failed to withstand high pressures and water surges typical in hydrant systems. Loctite 567 PST Thread sealant seals and secures metal pipes and fittings to ensure 100% leak proof joints.

Outperforms PTFE Tapes & Copper Washer
A leading manufacturer of CNC machines used PTFE tapes to seal the threaded joints at the oil filter inlet and outlet manifold. But the PTFE tapes shredded while assembling, some of these shreds get into the system and the customer was receiving field complaints of oil filter being blocked with shreds of PTFE tapes. Loctite 542 anaerobic thread sealant designed to seal fine threads was recommended for this application. It gave 100% sealing of threads - filling the thread imperfections and gaps and creating a leak proof joint thus creating additional savings in costs.
