Four-wire spiral hose for high-pressure main circuits — the backbone line for construction, mining, agricultural and forestry machinery, and injection-molding hydraulics.
Where pressure peaks and surges punish lesser hose, VR12's four spiral layers of steel wire carry the load — rated to 1,000,000 impulse cycles even in the standard grade.
Tube
Oil-resistant synthetic rubber, for petroleum- and water-based hydraulic fluids.
Reinforcement
Four spiral layers of high-tensile steel wire for sustained high-pressure duty.
Cover
Abrasion- and weather-resistant synthetic rubber. Smooth cover on VR12-PRO.

Std Reel = one standard reel length per size — our minimum order is one reel. Full material spec and temperature range available on request.
The Premium Grade
Step up to VR12-PRO.
The isobaric upgrade: a constant 4,060 PSI across every size, with the bend radius cut by 30–50%, an abrasion-resistant smooth cover, and MSHA flame resistance — for compact, high-cycle installs.
Send us your sizes and quantities — we'll come back with pricing and lead time. Hose ships by the reel (minimum one reel per size). Private-label inquiries welcome.
