Autoclave PT4440 Pipe Tee
Instrument Pipe Fittings, to 15,000 psi
Principle of Operation:
Parker Autoclave Engineers use high quality UNS S31600/S31603 316/316L material cold worked to our stringent specifications that enable certification of NPT style Instrument Pipe Fittings to a maximum working pressure of 15,000 psi. It’s the strength of the material that allows this superior pressure rating and care should be taken to only use with other similar fittings made to the same specification.
Pipe Fitting & Nipple Features:
- 1/4″, 3/8″ and 1/2″ NPT sizes to 15,000 psi.
- 3/4″ and 1″ NPT sizes to 10,000 psi.
- Barstock Fittings and Pipe Nipples manufactured using UNS S31600/S31603, 316/316L stainless steel material cold worked to Parker Autoclave proprietary standards.
- Operating Temperatures from -423F to +400F.
- Special materials available upon request or when NACE/ISO 15156 requirements demand. Note: 316 SS NACE Material (Annealed) reduces pressure rating for all sizes NPT to 10,000 psi MAWP.
- NPT threads made to ANPT (Aerospace) standards and based on requirements of ANSI B1.20.1.
- All Parker Autoclave Engineers fittings are marked with manufacturers name, part number, material, heat code and maximum pressure for complete traceability.
- Instrument Pipe Fittings and Nipples are designed using ASME B31.3 Chapter IX High Pressure Piping Standards to be compatible with our 10P and 15P P Series Needle Valves and all of our various Ball Valve configurations.

Note about NPT Pipe Thread Connections: NPT threads must be sealed using a high quality PTFE tape (3 wraps minimum) and/or thread sealant paste product suitable for process temperature. Refer to thread sealant manufacturer’s instructions for application instructions. A good thread lubrication product (metal flake style) capable of process temperatures is also necessary to prevent thread galling. Sealing performance may vary based on many factors such as pressure, temperature, media, thread quality, thread material, proper engagement, and proper use of thread sealant. End user should limit the number of times an NPT fitting is assembled and disassembled as thread deformation during assembly will result in deteriorating seal quality over time.
