Product Description

PA RL37 Premium High Pressure Spray Gun – 5000 PSI Wash Gun

Experience the pinnacle of Italian fluid-handling engineering with the PA RL37 Premium High Pressure Spray Gun. Designed for the most demanding, heavy-duty industrial cleaning applications, this elite pressure washer spray gun effortlessly manages immense hydraulic forces, officially rated for continuous operation at 4500 PSI, and capable of safely absorbing violent spikes up to 5000 PSI. Whether you are blasting thick concrete slurry off construction equipment or stripping heavy marine growth from commercial shipping vessels, this heavy-duty trigger gun guarantees unyielding reliability and flawless water control.

Operator comfort and fatigue reduction are paramount during long commercial shifts. To combat the agonizing wrist strain caused by wrestling with stiff, highly pressurized rubber hoses, the RL37 is factory-fitted with a premium 3/8" BSP Female Swivel on the inlet. This live swivel allows the gun to rotate completely independently of the hose, completely eliminating hose kinks and heavy drag. Constructed with high-grade internal brass and stainless steel valves capable of handling a massive 40 Litres per minute flow rate and scalding 160°C hot water, this power washer gun is the ultimate ergonomic upgrade for professionals who refuse to compromise on their equipment.

Who Is This High Pressure Spray Gun Ideal For?

The PA RL37 provides extreme 5000 PSI pressure handling and anti-kink swivel technology. It is highly recommended for:

Commercial Exterior Cleaners: Eliminating severe wrist and shoulder fatigue during 8-hour shifts by utilizing the built-in swivel to stop their heavy 30m hoses from twisting into tight knots.
Industrial Hot Water Users: Upgrading their pressure washer spray gun to a model with high-grade internal seals capable of safely managing boiling hot water and steam (up to 160°C) from HDS machines.
Mining & Earthmoving Wash Bays: Utilizing a power washer gun with massive internal flow capacity (40 L/min) to aggressively flush thick, abrasive clay from heavy machinery without restricting the pump.
Appliance Repair Technicians: Sourcing authentic, premium Italian-made trigger guns to professionally upgrade and refurbish clients' commercial pressure washing rigs.

Key Features and Performance Benefits:

Extreme 5000 PSI Capacity: Specifically engineered with heavy-duty internal valves to safely withstand the violent pressure spikes generated by the largest commercial petrol and diesel machines.
Integrated 3/8" Live Swivel: The base of the handle features a built-in brass swivel. This allows the hose to untangle itself as you walk, completely preventing kinks and drastically reducing arm fatigue.
Massive 40 L/min Flow Rate: The wide internal bore ensures absolutely zero restriction or back-pressure, allowing high-volume industrial pumps to operate at maximum efficiency.
Scorching Heat Tolerance: Designed to safely handle boiling hot water and steam up to 160°C (320°F), making it an indispensable tool for heavy-duty industrial degreasing operations.
Premium PA Italian Quality: Manufactured by PA, a globally revered Italian brand renowned for producing the most durable, reliable high-pressure fluid valves in the industry.

Frequently Asked Questions

What is the benefit of the built-in swivel on the inlet?

When a pressure washer hose is fully pressurized, it becomes incredibly stiff. As you walk around a vehicle, the hose twists and fights against your wrist, causing severe fatigue. The built-in swivel allows the gun to rotate freely in your hand, completely eliminating hose twisting and wrist strain.

What does '1/4 inch BSP Female Outlet' mean?

This is the screw thread at the front of the gun where you attach your long metal lance. It is a 1/4-inch British Standard Pipe thread. Because it is a 'Female' fitting, the threads are on the inside, meaning you must screw a 'Male' lance pipe into it.

Will this power washer gun fit my domestic Karcher or Gerni?

No. Domestic electric pressure washers use proprietary plastic push-and-click fittings. This commercial gun features heavy-duty brass screw threads (BSP) and will not connect to domestic hoses or lances without highly specialized adapters.

Is this safe to use on a massive 4000 PSI machine?

Yes, absolutely. The RL37 is officially rated for continuous operation at 4500 PSI, and can safely handle the sudden 5000 PSI 'spike' that occurs the exact moment you release the trigger.

Can I run boiling hot water through this gun?

Yes. This premium Italian pressure washer spray gun is engineered with high-temperature seals and metals that can safely withstand boiling water and steam up to a massive 160°C, perfect for HDS machines.

Why is the gun leaking from the front where the lance connects?

Because BSP threads are tapered metal-to-metal seals, you MUST wrap a few layers of Teflon (plumber's) tape or use a liquid thread sealant on the male threads of your lance before screwing it into the front of this gun to ensure a watertight seal at 4500 PSI.

Is the trigger easy to pull?

Yes. Premium PA guns are designed with advanced internal pivot mechanisms that drastically reduce the physical finger strength required to hold the trigger open, significantly reducing hand cramps during an 8-hour shift.

Why is my gun vibrating and making a loud chattering noise?

If the gun chatters or vibrates violently, it usually means the internal valve seat has been scored or damaged by sand or hard water scale bypassing your filter. The internal valve kit will need to be replaced.

Can I screw a Quick Connect plug directly into the front of this gun?

Yes! Many professional detailers create a 'short gun' setup by screwing a 1/4-inch Male Quick Connect plug into the front of this gun, allowing them to snap foam cannons and short nozzles directly into the handle.

Who manufactures PA guns?

PA is a highly prestigious, specialized fluid-mechanics engineering company based in Italy. They are globally recognized as the industry leader in commercial pressure washer valves, guns, and unloader systems.

Do you offer trade discounts for commercial cleaning companies?
