McKillans Pressure Washer Quick Connect Kit M22‑14mm to 3/8" Brass with Viton O‑Rings, Male & Female Adapters

McKillans Pressure Washer Quick Connect Kit converts standard M22‑14mm gas‑washer fittings to 3/8" quick disconnects using durable brass adapters and Viton O‑rings for leak‑resistant performance.

This all‑in‑one kit is designed to give you reliable quick‑connect functionality on gas pressure washers that use M22‑14mm hoses. Instead of hunting down individual parts, the McKillans kit supplies matched male and female M22 plugs, garden hose quick connects, and upgraded Viton O‑rings so your fittings mate smoothly and resist chemical and temperature wear. The components are precision machined from brass to reduce galling and corrosion common with lower‑grade materials.

How does this kit improve my pressure washer setup?

The kit swaps threaded M22 connections for quick disconnects, letting you change accessories faster and more cleanly. Brass construction and Viton O‑rings extend service life and reduce leak points compared with stock fittings.

• Instant quick‑disconnect conversion for M22‑14mm gas washer hoses
• Brass parts resist corrosion and mechanical wear
• Viton O‑rings handle heat and cleaning chemicals longer than standard rubber
• Includes both male and female connectors to cover multiple use cases

Which pressure washers will this McKillans kit work with?

It is compatible with gas powered pressure washers that use the common M22‑14mm hose standard. It will not fit machines that require a 15mm M22 plug, which some electric brands use.

• Works with virtually all gas pressure washers using M22‑14mm fittings
• Not compatible with M22‑15mm electric washer hoses (e.g., some Sun Joe, AR Blue models)
• Check plug diameter (14mm vs 15mm) before buying to prevent leaks
• Includes adapters and garden hose quick connects for flexible setups

What hardware and seals are included and why they matter?

The kit bundles the commonly required adapters and QC fittings so you don’t buy parts piecemeal. Each metal fitting is machined brass for dimensional accuracy while Viton seals provide chemical and heat resistance for longer life.

• 2 × M22‑14mm male plugs and 2 × M22‑14mm female quick connects
• 2 × male garden hose plugs and 2 × female garden hose QC fittings
• Viton O‑rings fitted to reduce swelling and chemical breakdown
• Precision machining for smooth, repeatable connections

How easy is installation and everyday use?

Installation requires screwing the supplied adapters onto existing M22 threads and pushing the quick connects together—no special tools beyond basic wrenches. Once installed, accessory swaps are typically a one‑hand job and you’ll spend less time fumbling threaded couplers.

• Simple thread attachment with common wrench sizes
• Quick disconnects engage and release quickly for faster accessory changes
• Brass machining reduces binding, easing repeated use
• Kit contains everything for common garden hose and pressure washer QC needs

Who is this for: The McKillans Pressure Washer Quick Connect Kit is aimed at homeowners and pros who use gas‑powered washers and want faster accessory changes, improved durability, and more reliable seals. Do not buy this kit for electric washers that require a 15mm M22 plug—measure your hose plug diameter first. If you want a single package that replaces multiple fittings with quality brass parts and upgraded O‑rings, this kit streamlines your setup and reduces downtime during cleaning jobs.
