It needs two fittings, 3/8 compression male and 3/4 in NPT male. Not many such fittings are on the market. This set includes 5, which is more than I need. But buying 1 or 2 is not cost effective. I hope they do offer more options. Anyway I'm satisfied with the quality of this fitting. ### ⭐⭐⭐⭐⭐ nice fittings! *by G***S on May 16, 2024* Fits tubing and pipe perfectly! ### ⭐⭐⭐⭐⭐ Fitment is very good *by S***Y on December 20, 2023* Fitment to mating sides is very good. Threads are formed very well with no seizing or interrupts. --- ## 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.pt/products/87507406-ltwfitting-brass-3-8-inch-od-x-3-8-inch](https://www.desertcart.pt/products/87507406-ltwfitting-brass-3-8-inch-od-x-3-8-inch) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-29*
