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 (1,050 bar). 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 materi-al, 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.
