The couplings shown here permit the joining of any combination of standard size tubing or tubing and standard pipe with female-to-female couplings. Other couplings available on special order.

Pressure Rating - The pressure rating of Autoclave couplings is based on the lower rated connection used.

Note: Special material couplings may be supplied with four flats in place of standard hex.

All Dimensions for reference only and subject to change.
For prompt service, Autoclave stocks select products. Consult your local representative.
All general terms and conditions of sale, including limitations of our liability, apply to all products and services sold.

Note: NPT (Pipe) connections
  • NPT threads must be sealed using a high quality PTFE tape and/or PTFE paste product. Refer to thread sealant manufacturer’s instructions on how to apply thread sealant.
  • 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.
  • Customer should 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, consider using thread lubrication to prevent galling of mating parts.
