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 ### ⭐⭐⭐⭐⭐ excellent product *by on Reviewed in the United States 11 January 2014* heavy duty product , easy to install on the compressor air hose and work very good any time wen i use my air finish gum to do carpentry job .the grip to disconnect is so so good i use my my new rubber air hose with this coupler and i feel happy. i can see this female coupler is for professional and heavy duty users . i recommend ,you will feel in your fingers the difference respect to others similar product . ### ⭐⭐⭐⭐⭐ Made in the USA quality *by on Reviewed in Canada 14 August 2022* I am buying more Milton made in the USA products, all the fittings at Home Depot are cheap Chinese junk. ### ⭐⭐⭐⭐⭐ Recomendado *by on Reviewed in Mexico 17 July 2026* Que todo es excelente excelente marca y producto --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sc/products/115876472-s-715-4-1-4-fnpt-m-style-coupler-pack](https://www.desertcart.sc/products/115876472-s-715-4-1-4-fnpt-m-style-coupler-pack) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-10-17*
