Coxreels P-MPL-420 Medium Pressure Spring Rewind Hose Reel | P Series | 1/2" Hose Diameter | 20' Hose Length | 2500 Max PSI | Less Hose

Built for medium-pressure work where flow volume matters as much as pressure rating, the Coxreels P-MPL-420 steps up to a 1/2-inch hose path while holding a 2,500 PSI working pressure — the right combination for high-volume pressure washing, larger-bore hydraulic feeds, and fluid transfer that would bottleneck through a 3/8-inch line. It's 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 1/2-inch I.D. line with a 13/16-inch O.D., up to 20 feet. The 2,500 PSI maximum working pressure (slightly lower than the 3/8-inch P-MPL models because the larger bore trades pressure capacity for flow capacity) handles medium-pressure water, hydraulic oil, and pressure washing duty at temperatures up to 212°F. The reel is sized 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 length suits fixed work positions where larger-bore flow matters more than reach. The "less hose" configuration lets you match hose material, fittings, and color to your specific service.

Features:

• Spring rewind retraction returns the hose to the reel automatically after use
• 1/2-inch I.D. hose path delivers higher flow volume than 3/8-inch medium-pressure reels
• 2,500 PSI maximum working pressure for medium-pressure water, oil, and pressure-wash service
• 212°F temperature rating supports hot water service (135°F max with synthetic fluids)
• Single-wire-braid hose path matches SAE 100R16 #1 reinforced hose specs
• Shipped less hose — fit your own 1/2-inch I.D. hose with 13/16-inch O.D. up to 20 feet

Applications

• High-volume pressure washing — wash bays running larger-orifice spray guns where 3/8-inch hose chokes flow at the nozzle
• Hydraulic service & test benches — larger-bore oil supply for component flushing, pump testing, and high-flow hydraulic fixtures
• Fleet & heavy equipment service — high-volume fluid delivery at fixed service positions for trucks, ag equipment, and construction machinery
• Industrial maintenance & MRO — medium-pressure utility drops where flow rate matters and 300 PSI low-pressure reels are underrated
• Mobile service trucks & trailers — truck-mounted larger-bore pressure-wash and fluid-service reels for field service rigs

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-420.

• Q: What hose specs do I need to match? A: Fit a hose with 1/2-inch inside diameter, 13/16-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 2,500 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: Why is the pressure rating 2,500 PSI on the 1/2-inch reel vs. 3,000 PSI on the 3/8-inch P-MPL-320? A: Larger-bore hose has a larger internal surface area, so for the same hose construction the burst-pressure margin is lower. Coxreels rates the 1/2-inch P-MPL-420 at 2,500 PSI to maintain the same safety margin the 3/8-inch reels carry at 3,000 PSI. Choose the 1/2-inch model when flow volume matters more than the top end of pressure; choose 3/8-inch when you need the full 3,000 PSI capability.

• Q: When should I choose 1/2-inch over 3/8-inch for medium-pressure work? A: Larger hose I.D. reduces pressure drop along the line and delivers more volume to the nozzle or fixture, which matters for high-flow pressure-wash guns, larger hydraulic cylinders, and fluid transfer applications where fill time matters. The trade-offs: 1/2-inch hose is heavier and stiffer, the reel maxes out at 20 feet (vs. 30 feet for the 3/8-inch P-MPL-330), and the pressure ceiling drops to 2,500 PSI.

• Q: Can this reel handle fuel or gasoline? A: No — the P-MPL-420 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.
