Shop by High Pressure Adapter Shape
High pressure fittings and adapters are essential components for managing and directing fluids in high-pressure applications. Our range includes Medium Pressure, High Pressure, Type M (Reverse High Pressure), NPT, BSP and JIC fittings, all known for their superior corrosion resistance due to high polishing. We offer custom-length thermoplastic high pressure hose assemblies, suitable for a variety of industries, including concrete removal, sewer cleaning, and hydrostatic testing. Manufactured in Houston, Texas, our fittings and adapters are designed to handle pressures from 10,000 psi to 60,000 psi, ensuring reliable performance in even the most demanding environments. Contact us today to find the right solution for your high pressure needs.
These adapters are for systems running from 10,000 to 60,000 PSI. Choose the shape first: straight, 90°, tee, cross, plug or cap, or the glands and collars that secure MP and HP connections. Then pick the connection on each side (MP, HP, Type M, NPT, BSP or JIC), keeping in mind that the rating depends on the connection type. For NPT, BSP or JIC ends, the thread identification guide helps. Under 10,000 PSI? See standard hydraulic adapters.
Frequently Asked Questions
When do I need high pressure adapters instead of standard hydraulic adapters?
When the working pressure reaches 10,000 PSI or more. The adapters in this section cover 10,000 to 60,000 PSI. OneHydraulics also offers custom-length thermoplastic high pressure hose assemblies for industries such as concrete removal, sewer cleaning and hydrostatic testing. Do not substitute standard hydraulic adapters in these lines; for systems below 10,000 PSI, the standard hydraulic adapter pages are the right place to shop.
What pressure does each high pressure connection type handle?
On the straight adapter page, the male connection types are listed up to these maximums: JIC 37° and NPT up to 15,000 PSI, MP (medium pressure) up to 20,000 PSI, BSP up to 30,000 PSI, Type M up to 50,000 PSI and HP (high pressure) up to 60,000 PSI. The rating of an actual part also depends on its size and material, so confirm it on the product page and size every component to the system's maximum working pressure.
What are high pressure glands and collars?
They are the parts that secure and seal MP and HP coned-and-threaded connections. The collar threads onto the threaded end of the tube, and the gland nut slides over the tube and threads into the fitting body, pressing the coned tube end into the seat. They are sold in Medium Pressure and High Pressure versions, so match them to the connection type.
What is Type M?
Type M, also called reverse high pressure, is one of the connection types offered alongside MP, HP, NPT, BSP and JIC. It is listed up to 50,000 PSI on the straight adapter page. Like the other types, it is not interchangeable with a different connection, so match each end exactly.
Do high pressure fittings need thread sealant?
Only on tapered threads such as NPT, which seal as the male and female threads wedge together and deform slightly; standard NPT needs thread sealant or PTFE tape to complete the seal. MP and HP coned-and-threaded connections seal metal to metal at the cone, and JIC seals at the 37° flare, so their threads hold the joint together rather than sealing it.
