The AirCraft Elbow W_o ring 4mm 1/4′ M PU Hose Fitting is a compact 90° push-to-connect elbow designed for clean pneumatic routing where space is limited and sealing matters. It connects 4mm tubing to a 1/4′ male BSP threaded port, and includes an O-ring seal to help improve leak resistance at the threaded connection. Ideal for regulators, manifolds, valves, air control blocks, and compact compressed-air installations, this elbow helps prevent kinks, reduces hose strain, and keeps your air line layout organised and professional.

Specifications

Features

• Integrated O-ring seal Helps improve sealing at the threaded connection for leak-resistant installs.
• 90° elbow profile Makes tight turns simple and keeps hose routing neat.
• 4mm push-in tube connection Quick installation with push-to-connect convenience.
• 1/4′ Male BSP thread Fits common pneumatic ports on regulators, manifolds, valves and fittings.
• Fast serviceability Release collar allows quick tube removal when the system is depressurised.

Benefits

• Better sealing confidence: The O-ring assists with leak resistance on the threaded joint.
• Cleaner hose routing: Reduces kinks and clutter in compact assemblies.
• Less strain on tubing: The elbow turn minimises bending stress and helps extend tube life.

Extra Information

• Made for 4mm outer diameter pneumatic tubing (commonly PU/nylon). Confirm tube OD before ordering.
• Ensure the threaded port is 1/4′ BSP (British Standard Pipe), not NPT.
• For best sealing, cut tubing square and clean and push fully into the fitting until it seats firmly.
• Inspect the O-ring before installation—replace if nicked, flattened, or damaged.

Safety

• Wear eye, ear and dust protection when working with air tools and pressurised lines.
• Depressurise the system completely before installing or removing pneumatic fittings.
• Confirm thread type (BSP vs NPT) before fitting—forcing the wrong thread can damage ports and cause leaks.
• Check tubing engagement with a gentle pull test after insertion to prevent blow-offs under pressure.
• Inspect the O-ring and replace if worn or damaged to maintain proper sealing.
