Home Improvement fittings that make pneumatic connections faster and more reliable for workshop and garage tasks. The oumuik Compressed Air Coupling pack uses brass quick couplings designed to reduce leaks and speed up tool changes. Is this set suited to someone who needs standard 3/8-inch fittings for everyday air tools?
⚡ At a Glance
- • Sealing Performance: High-quality brass and precisely cut threads aim to minimise leaks under pressure
- • Best for: DIY enthusiasts, tradespeople and small workshops using standard 3/8-inch pneumatic tools
- • Not ideal for: Specialist systems requiring non-standard thread sizes or integrated shut-off valves
Brass male-thread quick couplings for 3/8-inch BSP TW connections. Slide-back collar snaps fittings into place for fast hookup.
Durable, corrosion-resistant connections - thanks to high-quality brass construction
Manufactured from brass with external male thread, the couplings resist rust while maintaining tight mating surfaces. Dimensions include a coupling plug length of 42mm, thread diameter 17.72mm and hose connector diameter 16.36mm, ensuring consistent fits.
Longer service life and fewer replacements when used in humid or workshop environments. Consistent thread tolerances help reduce the chance of slow leaks.
Faster tool changes - with a slide-back collar quick-coupling mechanism
A push-to-connect action is achieved by sliding the collar back, inserting the mating fitting, then releasing the collar to engage internal locking elements. The male thread type is specified as 3/8" BSP TW for compatibility.
Swapping pneumatic tools becomes a few-second task, useful when changing between air tools on busy jobs. Less fumbling means less interrupted work and fewer accidental disconnections.
Works with standard fittings - thanks to the 3/8-inch BSP TW specification
The coupling plug uses a 3/8" BSP TW male thread, a common nominal width for pneumatic tool connections. The hose connector diameter of 16.36mm matches typical 3/8-inch hose inner dimensions.
Straightforward compatibility with standard pneumatic lines and tools avoids the need for adapters. Ideal for workshops that follow standard sizing conventions.
