5000 PSI A-Frame Hose Reel 1/2" x 300' DHRA50300SS

DHRA50300SS A-Frame Hose Reel, 300 Feet at 5000 PSI

The DHRA50300SS A-frame hose reel is the storage piece for crews running the heavy stuff, from pressure washing to agricultural spraying to plant and facility work. The stainless drum swallows 300 ft of 3/8 in. high pressure hose, which buys you serious working range without dragging the machine to a new spot every twenty minutes. Both the inlet and outlet run 1/2 in. FPT, so flow is not choked at the fittings. Commercial parking lots, fleet vehicles and municipal infrastructure are where it earns its keep.

Features

• Capacity for 300 ft of 3/8 in. line, so you park the rig centrally and still reach the far side of a warehouse or the top of a building
• Dual leg chassis stays planted when you crank in a long, water filled line, unlike single arm designs
• Safe working pressure up to 5000 PSI, which suits the larger commercial pumps
• Half inch plumbing front and back cuts friction loss right at the swivel
• Protects your line from kinks, wear and outright damage in the field
• Fewer loose coils underfoot means fewer trip claims on customer property
• Wide base with pre-drilled holes fits trailers, flatbeds and shop floors
• Adjustable tension brake sets the drag on the spool

Specifications

Why the Frame Shape and the Half Inch Plumbing Matter

Two legs were chosen for structural reasons, not looks. That shape absorbs the torque and vibration that hit the unit every time somebody rewinds, which makes for smoother turning and slower wear on the whole assembly. On the plumbing side, the half inch path through the swivel keeps friction loss down where it costs you the most. Your pump gets to put its cleaning power out at the gun instead of burning it inside the fittings, and that shows up on very long runs.

Swivel, Drum, Crank and Brake

The heart of the system is the heavy duty swivel, rated at 5000 PSI with 1/2 in. female pipe thread on both ends. Pros running pumps at 5 GPM and up need that, because the wider internal geometry cuts turbulence that a smaller swivel creates. The drum carries 300 ft of 3/8 in. line with room left to change hose configuration depending on the outside diameter you prefer. Rolled edges all the way around keep the jacket from getting cut or snagged, and the crank handle is welded to the axle so long winds do not punish your back. A friction brake assembly lets you dial in spool drag, which is what stops a bird nest from forming while you drive.

Mounting and Plumbing It In

Bolt this thing to something solid, meaning a trailer deck, a truck bed or a concrete floor. Loaded with line and full of water it can easily top 100 pounds, and that weight is exactly what works a weak mount loose when you travel or wind hard. Grade 8 bolts plus one or two large backing plates handle it. For plumbing, run a high pressure jumper from your pump to the 1/2 in. FPT inlet swivel and use quality thread sealant or PTFE tape so the joint stays dry at full pressure.

Wear Parts and Upkeep

The only moving part living under high pressure is the swivel, and it is designed so a leak turns into a quick repair rather than a new purchase. Seal kits are easy to source and go in fast. Keep the frame rinsed off now and then. The drum bearings turn freely on their own, but an occasional shot of grease at the zerks, or a spray lubricant if there are none, keeps everything rolling. Mounted properly and maintained a little, this unit will outlive several hoses.

Common Questions

The title reads 1/2 in. x 300 ft. Does it hold 300 feet of 1/2 in. hose?

No, and this trips people up. The half inch figure describes the plumbing, not the line. Inlet and outlet are both 1/2 in. FPT, while the drum is rated to store 300 ft of 3/8 in. high pressure hose. We list the spec version above because that is what the unit actually does.

So how do I connect my 3/8 in. hose to a 1/2 in. outlet?

Add a 1/2 in. male to 3/8 in. female reducer bushing at the outlet on the inner drum. That is a common fitting and it makes the final connection.

What pressure will it take?

Working pressures up to 5000 PSI, which covers the big commercial pumps.

What is the brake for?

It adjusts how freely the spool turns, so the reel stops when you stop instead of throwing loose line on the ground.
