5310 | 1/4 in Male Steel Plug Quick Connect

5310

The AR North America 5310 is a compact, heavy-duty
1/4″ male quick-coupling plug designed for professional
pressure washer systems and high-pressure cleaning equipment. Machined from
durable steel and rated up to 4,000 PSI and
300°F, this plug is built to handle demanding wash environments,
frequent connect/disconnect cycles, and the rigors of contractor or industrial use.

Featuring a 1/4″ quick-coupler plug profile with a
1/4″ male NPT thread, the 5310 is ideal for adapting spray
guns, lances, and accessories into quick-connect systems. It provides a reliable,
leak-resistant connection point between your pressure hose and high-pressure tools,
helping operators swap nozzles, guns, and specialty attachments in seconds without
tools or tape.

5310 Design & Construction

Heavy-Duty Steel Body

• All-steel construction delivers excellent strength and impact resistance in field use.
• Precision-machined sealing surfaces ensure a tight, drip-free connection with compatible 1/4″ quick couplers.
• Durable finish helps protect against rust, abrasion, and surface wear in wet and dirty environments.
• Engineered for use with cold-water and moderate hot-water systems up to 300°F when properly installed.

Compact, Versatile Form Factor

• 1/4″ quick-coupler plug profile fits most standard pressure washer quick-connect sockets.
• 1/4″ M NPT threaded end allows easy installation into spray guns, lances, manifolds, and accessories.
• Short overall length keeps assemblies compact and maneuverable, especially on spray guns and wands.
• Ideal as a universal “male end” adapter for building or standardizing quick-connect tool sets.

Applications & Use Cases

Pressure Washer Systems

• Contractor-grade cold-water units running up to 4,000 PSI for concrete, building, and surface cleaning.
• Shop and fleet wash bays where operators swap between different guns, lances, and specialty tools.
• Rental pressure washers needing rugged, easy-to-use quick-connect fittings that stand up to abuse.
• DIY and prosumer systems upgrading from threaded-only connections to quick-connect convenience.

Guns, Lances & Accessories

• Installing the 5310 into the inlet of a spray gun so it can snap directly into a 1/4″ quick-coupler hose.
• Adapting short lances, turbo nozzles, foamers, and specialty tools so they can be quickly changed in the field.
• Building accessory kits where a single hose and coupler can work with multiple attachments.
• Standardizing mixed equipment fleets to use the same 1/4″ QC interface across brands and models.

5310 Installation & Compatibility

Threaded Connection

• Thread the 1/4″ M NPT end into any compatible port—commonly the inlet of a spray gun or accessory.
• Use PTFE thread sealant or tape rated for high-pressure water service for leak-free performance.
• Do not over-tighten; follow typical torque practices for 1/4″ NPT steel fittings to avoid cracking the mating component.

Quick-Coupler Side

• Insert the 1/4″ quick-connect plug into a matching 1/4″ female quick coupler until it clicks firmly.
• Verify the coupler’s retaining sleeve fully engages the plug groove before pressurizing the system.
• To disconnect, pull back the coupler’s sleeve and withdraw the 5310 plug.
• Compatible with most industry-standard 1/4″ quick couplers found on professional pressure washer hoses.

Best Practices, Maintenance & Safety

Operating & Care Guidelines

• Always confirm your system pressure and temperature are within the 4,000 PSI / 300°F rating of the fitting.
• Inspect plugs and couplers regularly for groove wear, deformation, or corrosion that could affect retention.
• Replace damaged or excessively worn fittings immediately to maintain operator safety and prevent hose or tool ejection.
• Keep the plug and coupler free of grit and debris to avoid accelerated wear and sealing problems.
• When stored, protect fittings from impact and chemical exposure to extend service life.
