This will fix it! *by L***. on May 17, 2025* I bought this regulator because my kid liked to wash his car every weekend. Like a kid, he would forget to turn the hose off. Well a hose will only hold 120psi for so long in the sun before it ruptures. This product could have saved me two $60 hoses if I bought it earlier. 50psi is plenty to water the plants and wash a car. Easy to screw on between the hose bib and the hose and it'll work like a charm. No leaks. Works as advertised, all brass construction for longevity. ### ⭐⭐⭐⭐⭐ Very nice *by R***R on August 18, 2024* Well made ### ⭐⭐⭐⭐ Great backup pressure regulator. *by C***K on April 10, 2023* Bought this as a back up. Tried it to make sure it would do work and it works perfectly. ## Frequently Bought Together - Watflow Lead-Free Brass, Water Pressure Regulator, Garden Hose Pressure Regulator, Pressure Reducer For Camper, Trailer, RV, Garden, Plumbing System, 40-50 psi, 3/4"Hose - Camco Brass Marine/RV Water Pressure Regulator – Protects RV Kitchen Small Appliances, Plumbing & Hoses – Reduces RV Water Pressure to Safe & Consistent 40-50 PSI – Drinking Water Safe (40055) - Camco Tastepure RV Water Filter - New & Advanced RV Inline Water Filter with Flexible Hose Protector - GAC & KDF Filtration - Made in USA - Camping Essentials for Fresh Drinking Water (40043) --- ## 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.us/products/307713977-lead-free-brass-water-pressure-regulator-garden-hose-pressure-regulator](https://www.desertcart.us/products/307713977-lead-free-brass-water-pressure-regulator-garden-hose-pressure-regulator) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-11-11*
