Threaded couplings, reducers and adapters for pressure lines

Threaded sleeves and reducers form the backbone of any pneumatic or hydraulic plumbing layout, connecting lines of different diameters without modifying the tubing itself. This category covers female-to-female adapters and reducing sleeves in standard NPT thread sizes ranging from 1/4 inch to 1/2 inch, suitable for compressed air installations, hydraulic power packs and fluid transfer systems.

Airpress supplies reducers that step down between common compressed air sizes, such as 1/4 inch to 3/8 inch and 3/8 inch to 1/2 inch internal thread, ensuring compatibility across regulators, filters, lubricators and quick couplers in any workshop air network. Hi-Force contributes high-pressure adapters rated for hydraulic applications, including NPT female-to-female couplings in 1/4 inch and 3/8 inch configurations and reduction pieces that bridge different port sizes on cylinders, pumps and rams.

These fittings are built for leak-free performance under sustained hydraulic pressure. Select based on thread size, pressure rating and whether you need a straight coupling or a reducing step between two different line diameters.
