A washing machine water inlet on the back of the machine uses a standard 34 𝟑𝟒-inch Garden Hose Thread (GHT) connection. This means standard washing machine hoses and valves typically feature a 34 34-inch female fitting on both ends to connect the machine to the wall.
Standard washing machine water inlet hoses typically feature 34three-fourths𝟑𝟒-inch (G34three-fourths𝟑𝟒) female threaded fittings on both ends. These screw directly onto the water inlet valve on the back of the machine and the standard laundry supply valve (or spigot) on the wall.
【Universal 3/4" Fit for All Washers】Featuring standard 3/4 inch zinc-plated steel nuts and brass nipples at both ends, our washer hoses seamlessly connect to any US washing machine, faucet, or spigot.
Brass Fittings
All our washing machine valves have 3/4" Male Hose Thread Outlets. Inlets range from 1/2" MIP, F1807 & F1960 PEX, or Push Fit.
Most washing machine hoses use standard ¾-inch fittings, but you can choose between straight ends or a 90° elbow design.
Yes, washing machine inlet hoses are considered universal in the U.S. and most other regions, as they almost universally use a standard 3/4-inch female hose thread (FHT) connector on both ends. These hoses fit most major washing machine brands and household water supply valves.
A 5/8" hose is larger than a 1/2" hose. Because 5/8 is mathematically greater than 1/2 (as 58=0.625 compared to 12=0.500), it has a wider inner diameter. This means the 5/8" hose can deliver significantly more water volume per minute.
When it comes to inlet valves the two main thread diameters is 1/2" and 3/8". 1/2" is the British standard thread size, so most inlet valves tend to be 1/2". 3/8" is almost always reserved for cisterns and inlet valves from European manufacturers, such as Geberit, Villeroy & Boch, Grohe, and Roca.
Washing machine inlet hoses connect the appliance to the water supply and are typically fitted with 3/4" BSP connections. At BES, we stock hoses in a range of lengths and colours, including blue hoses for cold water and red hoses for hot water, from 1.5m to 3.5m to suit different layouts.
The standard size for washing machine water inlet hoses is 𝟑/𝟒 inch on both ends (Female Hose Thread). The internal diameter of the tubing itself is typically 1/2 inch. Drain hoses generally have an outer diameter of about 𝟏𝟏𝟒 inches.
Regardless of the hose sizes or types, be it rubber, vinyl, 1/2” to 3/4”, even those super stretchy, expanding hoses, they all have the same exact thread type in plastic, steel, solid brass, aluminum, still 3/4GHT. It's 3/4 hose thread which is similar diameter, but coarser thread pitch than 3/4 npt.
Standard washing machine inlet hoses are typically have 19mm or 3/4 inch fittings.
Measure Across the Opening: For a caliper, place the jaws inside the pipe (inside diameter) or around the outside (outside diameter), depending on what the component specs call for. With a tape measure, wrap it around the outside and divide by 3.14 to get the diameter.
Two hoses, likely for hot and cold water, are attached to the back of the washing machine and connected to the corresponding water supply valves on the wall. The red valve signifies hot water, while the blue valve represents cold water. These hoses deliver water to the washing machine during its cycles.
To measure the diameter of your water inlet pipe, take a 15 cm piece of string, wrap it around the exposed pipe, and then measure its length. Next, use the provided table to determine the diameter based on the pipe type (copper, steel, PVC, or PEX) and the measured length.
The wrong size could mean you might not have enough water pressure to get the job done properly. A 5/8” vs. 3/4" hose can mean a vast difference in the amount of water pressure your hose generates. Pressure is something you have to consider, especially if you intend to use your hose for outdoor cleaning projects.
What is Dash Sizing? Simply put, a dash size refers to the inside diameter of a hose, tube, or fitting in 1/16” increments. For example, if the size of a hydraulic fitting is -8AN, sometimes written as -08, the fitting is 8/16ths of an inch. Simplified down, the size of the hole is 1/2”.
If the inner diameter is approximately 15.88 mm, it is a 5/8-inch hose—commonly used for home gardening or car washing. If the measurement is 19.05 mm, it is a 3/4-inch hose—typically used for large-scale garden irrigation or commercial applications.
Washing Machine Inlet Pipe, 1.5-6 m, Size: 1.5 to 2 inch.
An M22 fitting is a threaded, metric connection widely used in the pressure washing industry to attach hoses, spray guns, and pumps. The "M" stands for a metric thread, and "22" indicates the outer diameter of the threaded connector is 22 mm.
Key Hose Connector Considerations
Yes, a 3/8" hose is larger than a 5/16" hose.
The best hoses for a washing machine are stainless steel-braided hoses. Unlike standard rubber hoses which are prone to swelling and bursting over time, braided steel hoses are highly durable, kink-free, burst-proof, and offer the best flood protection for your laundry room.
