50 ft Cold Water Hose
This 50 ft cold water hose is built for pressure-washing tasks where a durable, flexible supply line is required. The 5/16 in inside diameter delivers consistent flow to compatible equipment. It suits professionals and DIY users who need a reliable replacement or extension for existing M22 fittings. The gray polyurethane cover resists abrasion during regular job-site use.
Brass M22 Couplings and Polyurethane Cover
Both ends feature brass M22 fittings, one female and one male, sized for 5/16 in connections. The coupled assembly arrives ready to attach without extra adapters. A polyester tube handles the 3,700 psi working pressure at 70 °F, while the polyurethane cover protects against kinks and surface wear. Stainless-steel reinforcement adds strength without sacrificing flexibility.
Upgrade from Worn or Shorter Hoses
This hose replaces damaged, leaking, or shorter lines that limit reach around vehicles or buildings. The 50 ft length reduces the need to move the pressure washer frequently. The jump is worth it when the current hose shows cover cracks, fitting corrosion, or pressure loss at the gun. Buyers needing a different diameter, thread type, or hot-water rating should look elsewhere.

Questions about this item
What pressure does the M22 fitting limit this hose to in practice?
The hose is rated for a maximum working pressure of 3,700 psi at 70 °F, and both ends use brass M22 fittings sized for 5/16 in hose.
What clearance and thread type are needed to mount the M22 ends?
Each end has a brass M22 fitting — one female, one male — with a 5/16 in hose bore, so the mating port must accept an M22 thread.
How do you fit the coupled assembly, and what step is often missed?
Thread the female M22 end onto the pump outlet and the male M22 end onto the gun inlet, then tighten both firmly; the common mistake is leaving one end hand-tight, which leaks under 3,700 psi.
