20m Rubber Air Hose Assembly
3/8" I.D. — RP 1/4" BSP Swivel Ends
Factory-crimped and pressure-tested to 21 bar / 300 psi. Built for continuous duty in workshops, garages, and industrial environments across the UK.
21 Bar Rated Factory Crimped Pressure Tested UK Stock Fast Dispatch
This 20-metre reinforced rubber air hose assembly is engineered for demanding compressed air applications where reliability is non-negotiable. The 3/8" (10mm) internal bore delivers high-volume airflow to power impact wrenches, spray guns, grinders, and other pneumatic tools without pressure drop. RP 1/4" BSP swivel end fittings rotate freely to eliminate hose twist and kinking during use — a critical feature in busy workshop environments. Every assembly leaves our facility factory-crimped and pressure-tested, ensuring a leak-free connection from day one.
Key Features
High-Flow 3/8" Bore
10mm internal diameter sustains maximum airflow to hungry pneumatic tools without pressure loss over 20 metres.
RP 1/4" BSP Swivel Ends
Rotating swivel fittings prevent hose twist and tangling, extending service life and improving safety on the workshop floor.
21 Bar Working Pressure
Rated to 21 bar / 300 psi working pressure with a 63 bar / 900 psi burst rating — a 3:1 safety factor for peace of mind.
Wide Temperature Range
Remains flexible and reliable from −15°C to +60°C, suitable for unheated workshops in all UK seasons.
Reinforced Rubber Construction
Multi-layer reinforced rubber resists abrasion, oil, and UV exposure — built to outlast cheaper PVC alternatives.
20 Metre Working Length
Generous 20m reach covers large bays and commercial workshops without the need for extension hoses or couplers.

Frequently Asked Questions
What does RP 1/4" BSP swivel mean?
RP denotes a parallel (non-tapered) BSP thread to ISO 228. The swivel design allows the fitting to rotate 360° independently of the hose, preventing twist and kinking during use. It connects directly to standard 1/4" BSP male fittings found on most UK compressors and air line accessories.
Is this hose suitable for my air compressor?
Yes — provided your compressor operates below 21 bar / 300 psi, which covers virtually all workshop and trade compressors. The 3/8" bore is ideal for high-demand tools such as impact wrenches, DA sanders, and spray guns. For light-duty inflation or blow-off work, a 1/4" bore hose may suffice.
Can I use this hose outdoors in winter?
Yes. The reinforced rubber compound remains flexible down to −15°C, making it suitable for unheated workshops, outdoor sites, and cold-weather working conditions common across the UK.
How is the hose assembled and tested?
Each hose is factory-crimped using hydraulic crimping machinery to ensure a permanent, leak-free seal between the hose and fitting. Assemblies are pressure-tested before dispatch — not simply assembled and shipped.
What is the difference between rubber and PVC air hose?
Rubber hose offers superior flexibility at low temperatures, better resistance to oil and abrasion, and a longer service life in heavy-use environments. PVC hose is lighter and lower cost but can stiffen in cold conditions and is less durable under continuous industrial use.
