Cone & Thread Adapters & Couplings

Parker Autoclave's Cone and Thread Adapters and Couplings are designed for use with Parker Autoclave medium and high pressure tubing. These Adapters and Couplings are rated up from 15,000 psi (1,035 bar) up to 150,000 psi (1,0342 bar). 

The male /female Adapters are designed to adapt a female connection to another size and/or type of connection without the need for additional couplings. In selecting an adapter involving two different sized connections, the larger connection should be on the male end where it is possible to maximize the mechanical strength of the adapter.

The Couplings are manufactured to permit the joining of any combination of standard size tubing or tubing and standard pipe with female-to-female couplings. The pressure rating of Parker Autoclave Couplings is based on the lower rated connection used.

NOTE: 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.
