Exceeds industry standard of 15,000 psi. Maximator® Pipe fittings are designed for liquid and gas applications. The P Series Fittings are available from 1/4" to 1" NPT to 15,200 psi. These are high pressure NPT fittings for pressures up to 15,200 psi.

NPT threads must be sealed using a high quality PTFE tape and/or paste product. Sealing performance may vary based on many factors such as pressure, temperature, media, thread quality, thread material, proper thread engagement and proper use of thread sealant.

Maximator® Recommends to limit the number of times an NPT fitting is assembled and disassembled because thread deformation during assembly will result in deteriorating seal quality over time. When using only PTFE tape, using thread lubrication to prevent galling of mating parts is recommended.
