Featuring 3/4-inch FPT threaded connections and a double O-ring seal, it ensures a secure, leak-proof fit. Built from durable brass with a protective lid, it withstands harsh underground conditions and pairs with the Orbit 51031 key for easy water control and maintenance. Ideal for residential and commercial landscapes, this valve supports efficient, long-lasting irrigation setups. ## 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 - Valve Body Only: Professional brass quick coupler valve for underground installation; pair with Orbit 51031 key sold separately - Pipe Thread Connections: 3/4 in FPT inlet for installation; key outlet requires 1/2 in MPT or 3/4 in FPT to MHT adapter for garden hoses - Secure O-Ring & Washer Seal: Double-seal design ensures watertight operation; requires firm push to insert key fully into valve - Corrosion-Resistant Brass: Durable brass body and protective lid withstand years underground - Professional Installation: Install on 3/4 in riser from pressurized mainline; use with 7 or 10 in round valve box at grade ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000PSAQAG | | Best Sellers Rank | #47,868 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #266 in Automatic Irrigation Accessories | | Brand Name | Orbit | | Connector Type | Threaded | | Customer Reviews | 4.6 4.6 out of 5 stars (615) | | Exterior Finish | Brass | | Global Trade Identification Number | 00046878510296 | | Included Components | 3/4" Brass Quick Coupler Valve | | Inlet Connection Size | 0.75 Inches | | Inlet Connection Type | National Pipe Tapered | | Item Dimensions | 3 x 2 x 4 inches | | Item Type Name | Brass Quick Coupler Valve | | Item Weight | 0.8 Pounds | | Manufacturer | Orbit | | Material Type | Brass | | Maximum Pressure | 150 Pound per Square Inch | | Model Number | 51029 | | Number of Ports | 2 | | Outlet Connection Size | 0.75 Inches | | Outlet Connection Type | MNPT | | Size | 0.75 Inch | | Specification Met | WaterSense | | Thread Size | 3/4-Inch | | Thread Type | FPT and MPT | | UPC | 046878510296 | | Unit Count | 1.0 Count | | Valve Type | Sprinkler Valve | ## Product Details - **Brand:** Orbit - **Exterior Finish:** Brass - **Inlet Connection Size:** 0.75 Inches - **Inlet Connection Type:** National Pipe Tapered - **Item dimensions L x W x H:** 3 x 2 x 4 inches - **Material:** Brass - **Maximum Operating Pressure:** 150 Pound per Square Inch - **Number of Ports:** 2 - **Outlet Connection Size:** 0.75 Inches - **Outlet Connection Type:** MNPT ## Images ![51029 Brass Quick Coupler Sprinkler Valve, 3/4 in FPT, Underground Irrigation - Image 1](https://m.media-amazon.com/images/I/7106zlS6yBL.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.
