The maximum pressure will be 300 PSI. **Q: Where is it made?** A: Mine says made in USA on packaging. Nothing listed on the part itself. I like mine, purchased several and all work good. Would buy again. **Q: If a single pack costs $4.68, why does a 2 pack cost $16.99 ??** A: Better quality or greed ## Customer Reviews ### ⭐⭐⭐⭐⭐ Made in the USA quality *by M***V on 14 August 2022* I am buying more Milton made in the USA products, all the fittings at Home Depot are cheap Chinese junk. ### ⭐⭐⭐⭐⭐ new one to fix 1/4 air pipe. *by T***G on 11 December 2022* I like it and using it. ### ⭐⭐⭐⭐⭐ Quality Machining Means Easy Fit and No Hissing *by J***G on 20 July 2025* Milton is the "gold standard" of air fittings in my 60+ years of using air for so many tools. It connects and disconnects without hissing all the time, like the leaky cheapies do. Very good quality and tolerances, make it easy to use, so I put male ends on the tools and female end on the hose and go to work. ## Frequently Bought Together - Milton (S-715) 1/4" FNPT Female M-Style KWIK-CHANGE Coupler , Red - Milton (S-716) 1/4" Male NPT M Style (Industrial) Air fitting Quick Connect Coupler (Packaging May Vary) - Milton Industries S-728 1/4" FNPT M Style Plug, Steel - 2 Count (Pack of 1) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/323156797-milton-s-715-1-4-fnpt-female-m-style-kwik](https://www.desertcart.jp/products/323156797-milton-s-715-1-4-fnpt-female-m-style-kwik) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-15*
