Crafted from durable brass with watertight O-rings and a double lug valve key combining brass and steel, it ensures reliable, leak-free operation. Compatible with standard 3/4-inch fittings, it’s the go-to choice for professional-grade landscape watering systems. ## Description Quick coupler valves and keys are a time-tested way of making it easy to access a pressurized line anywhere in a landscape, while keeping it safe and secure. For that reason, it is very common to see them at golf courses and commercial properties, although you will see them in residential applications, too. The valve is made of durable brass, including the lid which prevents debris from entering the valve. The durable O-rings are serviceable and replaceable. The inlet threads are 3/4-inch female pipe thread (FPT). Typical installation is on a 3/4-inch riser from a 3/4-inch mainline (continuously pressurized) tee or elbow fitting. It is common to place a 7- or 10-inch round valve box, with lid at grade level, over the valve. The double lug valve key has a durable brass body and a steel handle. Insert it into the valve and turn clockwise to turn the water on, and counterclockwise to turn it off. The outlet threads of the key are 3/4-inch male pipe thread (MPT). You can adapt it to hose thread with a 3/4-inch FPT x 3/4-inch MHT brass hose-to-thread fitting, making sure to apply pipe tape to the MPT threads on the quick coupler. For outdoor irrigation use with cold water only. Review: QRV Key - Good Value - Very good quality and value for money. Heavy brass and works great. Review: Worked like a charm - Worked like a charm to connect to a Turfgro 3/4 inch Quick Coupler Valve to do a sprinkler winterizarion. Prefer this model because of the removable T bar. Our valve is in a casing too narrow to use the T bar, so if it was permanently fixed, it wouldn’t work for us. ## Features - For creating a fast, easy connection to a pressurized line anywhere in a landscape - Made of durable brass body and lid which prevents debris from entering - Durable O-rings ensure a watertight seal between valve body and key - Double lug valve key is made from a combination of brass and steel - Compatible with Orbit Quick Coupler Valve and 3/4-inch MPT fittings at outlet ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000VYB04U | | Best Sellers Rank | #42,547 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #267 in Automatic Irrigation Accessories | | Brand | Orbit | | Brand Name | Orbit | | Customer Reviews | 4.6 out of 5 stars 615 Reviews | | Exterior Finish | Brass | | Global Trade Identification Number | 00046878510319 | | Included Components | Quick Coupler and Lever | | Inlet Connection Size | 0.75 Inches | | Inlet Connection Type | Female Iron Pipe | | Item Dimensions | 1.75 x 1 x 6 inches | | Item Type Name | Watering Equipment Tool | | Item dimensions L x W x H | 1.75 x 1 x 6 inches | | Manufacturer | Orbit | | Manufacturer Part Number | 51031 | | Material | Brass | | Material Type | Brass | | Model Number | 51031 | | Number of Pieces | 1 | | Number of Ports | 2 | | Outlet Connection Size | 0.75 Inches | | Outlet Connection Type | MPT | | Size | 3/4 inches | | Smart Home Compatibility | Not Smart Home Compatible | | Thread Size | 3/4 inches | | Thread Type | Pipe Thread | | UPC | 046878510319 | | Unit Count | 1.0 Count | | Valve Type | Quick Coupler | ## Product Details - **Material:** Brass - **Brand:** Orbit - **Item dimensions L x W x H:** 3 x 1 x 10.13 inches - **Exterior Finish:** Brass - **Inlet Connection Size:** 0.75 Inches - **Inlet Connection Type:** Female Iron Pipe - **Outlet Connection Type:** MPT - **Number of Ports:** 2 - **Outlet Connection Size:** 0.75 Inches - **Global Trade Identification Number:** 00046878510319 ## Images ![51031 Brass Quick Coupler Sprinkler Key - Image 1](https://m.media-amazon.com/images/I/510jT7gSpfL.jpg) ![51031 Brass Quick Coupler Sprinkler Key - Image 2](https://m.media-amazon.com/images/I/71Yh6tfCuBL.jpg) ![51031 Brass Quick Coupler Sprinkler Key - Image 3](https://m.media-amazon.com/images/I/61AfjAAy7NL.jpg) ![51031 Brass Quick Coupler Sprinkler Key - Image 4](https://m.media-amazon.com/images/I/71OG86ArGtL.jpg) ![51031 Brass Quick Coupler Sprinkler Key - Image 5](https://m.media-amazon.com/images/I/41Kg4RCvnDL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ QRV Key - Good Value *by M***K on May 22, 2025* Very good quality and value for money.

I bought one of these on Amazon 2 years ago to install near my kids' raised garden so they wouldn't have to drag the heavy hose out there all the time. It worked out great and has done fine over the years. I installed it underground within a round box, so it's well protected; therefore, I can't comment as to the durability to external forces. I just ordered a second one to install elsewhere in my yard, and I see that the cover is now made of brass -- the old one is made of a flexible plastic (almost rubbery). It seems like the old plastic cover would do better to keep out debris since it has a large lip that goes down around the valve. Although, I can see the metal cover probably being more durable and do better against external forces, which would probably be good if you just install it in the open (not in a buried box). I'm thinking of installing this new valve without a box (almost flush with the ground), and if I do, I will be sure to update this review after a year or so to see how well it holds up. ## Frequently Bought Together - Orbit WaterMaster Underground 51031 3/4-Inch Brass Quick Coupler Key - Orbit WaterMaster Underground 51029 3/4-Inch Brass Quick Coupler Valve - Eastman Bent Nose Garden Hose Valve, 3/4 Inch FIP x 3/4 Inch MHT, Brass Plumbing Fitting, 20253 --- ## 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.ec/products/4254532-51031-brass-quick-coupler-sprinkler-key](https://www.desertcart.ec/products/4254532-51031-brass-quick-coupler-sprinkler-key) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-06-18*
