{"type":"firestarter.listing","listing":{"id":"lst_BbQ48chT","product_name":"Mosmatic T304 SS 3/8\" Female QD Coupler","category":"Detailing Equipment","description":"I worked closely with Jaimie from Mosmatic US to have these high-end quick disconnects made for us, the discerning prosumer. The Mosmatic T304 SS 3/8\" Female QD Coupler would be used on a High-Pressure Hose or any other 3/8\" fitting that's NPT threaded.\nI wanted these T304 stainless fittings at any cost, and my guess is that many of you do too. I get that this is more expensive than brass or Chinese-made stainless, but the fit, finish, and precision makes it worth it. These fittings are special because they're manufactured in Switzerland with much greater precision than typical fittings.\nAll of my new Mosmatic fittings come with a 6-month warranty, but I suspect they'll last for quite a while. These couplers have a satisfying action to them, and even the sound they make sounds stout.\nDo keep in mind that these are a consumable. These are like tires that will be susceptible to wear and tear and future replacement. They are just much better than normal.\nSpecifications\n- Brand: Mosmatic\n- Material: T304 Stainless Steel\n- Inlet: ⅜\" Female NPT\n- Outlet: ⅜\" QD Coupler\n- Warranty: 6 months, for manufacturing defects (does not include o-rings).\n\nFAQ & Support\n\nWhy is my 3/8\" coupler leaking from the end?\nPressure Washer Fittings 101: Fittings and QD Naming\nPressure Washer Fittings 102: Applications and Usage\nPressure Washer Fittings 103: Spray Nozzles\nInstallation:\nTo install your female 3/8\" couplers on the ends of your High-Pressure hose (or other 3/8\" NPT terminated hose) you will need the following: 1.
