Tools Pressure Washer 1/4 inch FNPT Refrigerator Quick Coupling Brass Washer Quick Connect Plug Fast, durable quickconnect plug made from solid brass. Designed to provide a reliable, leakresistant connection for pressure washer systems and refrigerationstyle quick couplers that use 1/4' FNPT fittings. Why you need it Speeds up tool changes and hose swaps: connect and disconnect in seconds without threading and unthreading. Builds a secure, lowleak seal for pressure applications: brass construction resists wear and maintains tight mating with standard 1/4' male NPT threads. Reduces downtime during maintenance and service work by enabling rapid attachment of accessories, hoses, and diagnostic tools. Key features and attributes Thread size: 1/4 inch FNPT (female NPT) — mates with standard 1/4' male NPT fittings. Material: solid brass body for corrosion resistance and long service life. Type: quick coupling / quick connect plug in refrigerationstyle configuration. Intended use: compatible with pressure washer fittings and refrigeration quickcoupling systems that accept a 1/4' FNPT plug. Simple installation: screws onto a 1/4' male NPT port; pairs with matching quick couplers for instant connection. Performance and compatibility Built for pressure environments commonly encountered with pressure washers and field service tools; brass construction withstands repeated connects and disconnects. Works with standard 1/4' male NPT threaded hoses, adapters, and couplers; suitable wherever a 1/4' FNPT quickconnect plug is specified. Compact design keeps the connection short and secure, helping prevent sprayback and leakage when mated with compatible couplers. Practical use cases Pressure washing: attach to wands, lance extensions, or accessory adapters to quickly swap nozzles and attachments on a pressure washer system. Refrigeration service and diagnostics: use with refrigerationstyle quick couplers and gauges that accept 1/4' FNPT quickconnect plugs for rapid pressure checks and refrigerant line connections. Workshop and field service: provide a fast, reliable connection point for portable pumps, test equipment, and service hoses that require 1/4' FNPT quick coupling. Installation tips Thread the plug onto a matching 1/4' male NPT port and handtighten, then finish with a wrench if needed. Use an appropriate thread sealant or tape recommended for your system to ensure a leak seal. Inspect coupler mating faces for debris and wear before connecting. if any damage compromises sealing performance. What makes it stand out Solid brass construction for durability and corrosion resistance. Standard 1/4' FNPT sizing ensures broad compatibility with pressure washer and refrigerationstyle quick couplers. Simple, reliable quickconnect functionality that reduces setup time and improves workflow for cleaning, maintenance, and service tasks.
