About Panam and Hiflux Cone-and-Thread Fittings

This catalogue brings Panam and Hiflux high pressure fittings together in one table for tubing systems that run far beyond the limits of ordinary compression fittings. Most items use a cone-and-thread connection: the tube end is coned and threaded, a gland and collar are made up onto it, and the seal forms metal-to-metal where the cone seats in the fitting body. The thread holds the tube in place rather than sealing the fluid, so the joint can be broken and remade during maintenance.

Panam fittings are SS 316 and cover 10,000 to 60,000 psi, with adapters, reducers, male and female connectors, elbows, tees, crosses, hex nipples, unions, reducing and bulkhead unions, caps and plugs in NPT, MP and HP cone connections. Hiflux fittings are cold-formed STS 316 and extend to 150,000 psi, alongside glands, sleeves, collars, collets and plugs, including anti-vibration accessory variants for high-vibration service. Typical uses include test rigs, chemical injection, waterjet equipment and laboratory high pressure systems.

Use the brand, fitting type, pressure rating, size and material filters to narrow the list, then request a quote. Valvenok's UK team in Bicester can confirm part numbers and lead times before you order.

• Pressure: pick a rating at or above the maximum working pressure of the line, including surges.
• Connection: cone-and-thread, MP, HP and NPT ends are not interchangeable, so keep them consistent.
• Size: the range runs from 1/8" to 1" and should match the tube outside diameter.
