It’s machined from 304 medical-grade stainless steel for corrosion resistance and longevity, and uses Viton O-rings for improved heat and chemical tolerance compared with standard rubber seals.

Hand-tightening plus a half-turn with an appropriate wrench is usually all that’s needed; avoid overtightening stainless threads to protect the O-rings.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eScrew the M22 female onto your hose or pump outlet\u003c\/li\u003e\n  \u003cli\u003ePush the 3\/8\" quick-connect into the mating male until it clicks\u003c\/li\u003e\n  \u003cli\u003eHand-tighten, then use a wrench for a final small turn\u003c\/li\u003e\n  \u003cli\u003eReplace O-rings as routine maintenance when worn\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho this is for: This kit suits homeowners, detailers, rental shops, and pros who need durable, leak-resistant quick-connects for gas pressure washers using M22-14mm fittings. If you want to eliminate mixed-fit frustrations, upgrade to corrosion-resistant hardware, and keep connections serviceable under heavy use, this set gives the essential adapters and quality materials to do that. Do not purchase if your pressure washer requires a 15mm fitting; verify your hose diameter first to ensure compatibility.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this fit my Sun Joe or other electric pressure washer?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. This kit fits M22-14mm plugs used on many gas washers; Sun Joe and some electric models use 15mm fittings and won’t seal correctly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What are the O-rings made from and why does it matter?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: O-rings are Viton, which resists higher temperatures and cleaners better than standard rubber, extending seal life.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"McKillans","offers":[{"title":"Default Title","offer_id":56837548573012,"sku":"B0BQZ1HC53","price":89.43,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1063\/2652\/4244\/files\/mckillans-front-packaging-quick-connect-kit.jpg?v=1787060095","url":"https:\/\/gardenluxe.co.uk\/products\/mckillans-pressure-washer-quick-connect-kit-m22-14mm-to-3-8-inch-304-stainless-with-viton-o-rings","provider":"Gardenluxe Uk","version":"1.0","type":"link"}
