Pneumatic and PU air hose — coiled self-retracting and straight braided types in 6–12 mm bore for vehicle workshops, factories, and construction sites across NE India.
A pneumatic air hose is the flexible conduit that connects a compressed air source — compressor outlet, air receiver, or workshop air drop point — to air tools, spray guns, blow guns, and pneumatic cylinders. It must carry compressed air at the required working pressure and flow rate without excessive pressure drop, kinking, or leakage at the couplings. Two main types are stocked at Multi Trade Combines: coiled PU (polyurethane) hose for flexible tool connections that require retraction, and straight rubber or PVC braided air hose for fixed air outlet drops and longer runs between the compressor and the work area.
Pneumatic hose is a consumable in any compressed-air workshop — subject to abrasion, accidental cuts, coupling wear, and UV degradation over time. Multi Trade Combines stocks pneumatic and PU hose in multiple bore sizes and lengths at our Industrial Spares counter in Guwahati, serving workshops, factories, construction sites, and automotive service centres across Northeast India.
Vehicle workshops and automotive service centres across Guwahati and the Northeast use coiled PU air hose on tool balancer drops from the ceiling, connecting to impact wrenches, air ratchets, blow guns, and tyre inflators at each service bay. The self-retracting coil keeps hose off the floor — reducing trip hazards and preventing hose damage from vehicle tyres. A busy workshop may have 8–15 coiled hose drops serving its service bays, each replaced every 1–2 years as coupling connections wear and the coil loses its spring memory.
Industrial production lines using pneumatic conveying, cylinder actuation, and air-powered tool feeds in packaging plants, food processing units, plywood mills, and garment factories across Assam use straight rubber braided air hose for high-pressure feeds to pneumatic panels and tool headers. The higher pressure rating of rubber braided hose suits these fixed, high-demand circuits where PU coiled hose would be undersized.
Construction sites across Northeast India use pneumatic hose to connect air compressors to pneumatic breakers, chipping hammers, spray mortaring equipment, and nail guns. The straight hose is dragged to the work face and coiled up at end of shift; robust rubber or PVC braided hose withstands the site environment far better than lighter PU hose. Multi Trade Combines stocks all these hose types — with compatible BSP couplings and fittings — for one-stop supply of pneumatic hose and accessories from our Guwahati counter.

A coiled polyurethane (PU) air hose is spring-coiled at rest and stretches to its full working length when pulled — typically extending from 0.5–1 m at rest to 5–10 m extended. It retracts automatically when tension is released, keeping the workshop floor clear of trailing hose and reducing trip hazards. It is the preferred choice for tool balancers, robotic air feeds, and any application where the hose must retract out of the work zone. A straight air hose (rubber or PVC) lies flat and must be coiled manually for storage; it is more suited to fixed tool points and air outlet drops where the hose stays in a fixed position. Coiled PU hose is lighter and more flexible than rubber hose at the same bore, but has a lower maximum working pressure rating — typically 10–12 bar versus 20+ bar for wire-braided rubber hose.
Standard PU air hose is rated for temperatures from -20°C to +60°C, making it suitable for most outdoor workshop use including cold winter conditions in the Northeast hills and summer workshop temperatures in the Brahmaputra valley. At temperatures above 60°C — near heat sources, welding operations, or direct exhaust contact — PU hose degrades and loses flexibility; use high-temperature rubber or silicone hose in these locations. UV exposure from direct sunlight over long periods causes some PU formulations to become brittle; route the hose away from direct sun or use a rubber-sheathed hose in permanent outdoor installations. PU hose is not suitable for compressed oxygen, acetylene, or other industrial gases — use only for compressed air.
