Built for medium-pressure air, water, and oil service where standard shop-air reels can't keep up, the Coxreels P-MPL-320 is a P Series Spring Rewind Hose Reel (a self-retracting reel that pulls hose back automatically when released) shipped without hose so you can fit your own. It accommodates up to 20 feet of 3/8-inch I.D. Hose with an 11/16-inch O.D., and the 3,000 PSI maximum working pressure (a tenfold jump over low-pressure shop-air reels) covers high-pressure water, hydraulic oil supply, and pressure washing duty at temperatures up to 212°F. The medium-pressure designation means this reel and its companion hose are built for SAE 100R16 #1 single-wire-braid hose specs — a reinforced construction that handles cycling pressure without ballooning or kinking under load. The 20-foot capacity is sized for fixed work positions where pressure and durability matter more than reach: pressure-wash bays, hydraulic test stands, and machine-side fluid drops. The "less hose" configuration lets you match hose material, fittings, and color to your specific service.

Applications
- Pressure washing & wash-down stations — hot- and cold-water pressure-wash bays in vehicle service, food processing, and equipment-rental yards
- Hydraulic service & test benches — oil supply drops for hydraulic test stands, pump test rigs, and component flushing stations
- Fleet & heavy equipment service — high-pressure fluid delivery at fixed service positions for trucks, ag equipment, and construction machinery
- Industrial maintenance & MRO — medium-pressure utility drops in plants, foundries, and fabrication shops where standard 300 PSI reels are underrated
- Mobile service trucks & trailers — truck-mounted pressure-wash and fluid-service reels for field service rigs and mobile detailing
FAQs:
- Q: Why does the model say "less hose" — what's in the box? A: "Less hose" means the reel ships bare without any hose installed. You purchase the hose separately and fit it to the reel. This lets you select hose material, fitting type, and color for your specific service. If you want a complete unit with the standard SAE 100R16 #1 hose pre-installed, the matching model is the P-MP-320.
- Q: What hose specs do I need to match? A: Fit a hose with 3/8-inch inside diameter, 11/16-inch outside diameter, and up to 20 feet in length. Coxreels furnishes the matching with-hose reel using SAE 100R16 #1 single-wire-braid hose, so use that standard (or better) to meet the 3,000 PSI rating and 212°F temperature limit. The 212°F maximum drops to 135°F when running synthetic fluids — confirm hose compatibility with your specific fluid.
- Q: What's the difference between low-pressure and medium-pressure P Series reels? A: Low-pressure P Series reels (P-LP / P-LPL models) cap at 300 PSI and 150°F — sized for shop air, water, and oil at standard utility pressures. Medium-pressure reels (P-MP / P-MPL) step up to 3,000 PSI and 212°F, with a reinforced hose path matched to single-wire-braid hose. Choose medium-pressure for pressure washing, hydraulic supply, and any service above 300 PSI.
- Q: Can this reel be used for hydraulic oil and grease? A: Yes for hydraulic oil up to 3,000 PSI and 212°F (or 135°F with synthetic fluids). For grease delivery specifically, Coxreels' high-pressure P-HP / P-HPL series is the typical fit — those are sized for SAE 100R16 #1 or #2 hose at 4,000–5,000 PSI to match grease-gun system pressures. Confirm your system pressure before selecting.
- Q: Can this reel handle fuel or gasoline? A: No — the P-MPL-320 is rated for air, water, and oil service only. For fuel delivery, select a Coxreels reel built with fuel-compatible seals. Using this reel with gasoline, diesel, or E85 can damage the swivel and create a leak hazard.
