HP Pipe Fittings — Size Adapters

Panam High Pressure Size Adapters in SS 316. Each adapter changes size only, with the same thread type at both ends: NPT to NPT, or ISO parallel (BSPP) to ISO parallel (BSPP). 10,000 to 15,000 psi. Sizes from 1/8" to 1".

About High Pressure Size Adapters

A size adapter joins two threaded ports of different sizes without changing the thread form. The Panam high pressure adapters listed here are machined from SS 316 and keep the same standard at both ends: NPT to NPT, or ISO parallel (BSPP) to ISO parallel (BSPP). They are useful when a gauge, transducer, valve or pump port does not match the size of the pipework it has to connect to, and they avoid stacking several bushings in a high pressure line.

Sizes run from 1/8" to 1" and ratings are 10,000 or 15,000 psi. The rating is shown on every row and is also built into the part number, where a suffix of 15K means 15,000 psi and 10K means 10,000 psi (for example PA-2N-4N-SS-15K is a 1/8" NPT to 1/4" NPT adapter rated to 15,000 psi). When a line mixes ratings, the lowest-rated component sets the limit for the whole assembly.

Thread form matters for sealing. NPT is tapered and seals on the thread flanks with a suitable sealant, while ISO parallel threads need a bonded seal or similar face seal to hold pressure.
