The most widely used for pressure washer hoses are 3/8-inch fittings. 1/4 inch: Used for smaller pressure washers and accessories. 3/8 inch: The most common size for residential and commercial pressure washers. 1/2 inch: Used for high-flow applications or larger pressure washers.
The diameter of threaded fitting inside a hose is referred to as the thread size. Hose diameters range from 3/8 inch, 1/2 inch and 3/4 inch. The bigger the diameter, the more water is delivered. The most common garden hose thread size is 3/4 inch.
Mid-sized (5/16”) hoses are the least common. They are rated for prosumer-grade gas pressure washers that can withstand pressures between 2,700-3,600 psi. Large (3/8”) hoses are designed for all professional models and some prosumer-grade gas pressure washers.
Most hoses use the standard ¾-inch FGH (female garden hose) fittings, making them compatible with most washing machines.

The most widely used for pressure washer hoses are 3/8-inch fittings. 1/4 inch: Used for smaller pressure washers and accessories. 3/8 inch: The most common size for residential and commercial pressure washers. 1/2 inch: Used for high-flow applications or larger pressure washers.
Hose diameters range from 3/8-inch, 1/2-inch to 3/4-inch. In the United States, most standard garden hoses are 5/8-inch in diameter. The bigger the diameter, the more water is delivered. The bigger the diameter determines how much hose can be put on any of our water hose storage products.
Dimensions? Inner diameter 2.3cm/1 inch, the hose end is connected to 2cm (0.8 inch), the total length of the drain hose is 2.5 meters, the diameter of the white adapter is 2.1cm (0.8 inch), suitable for direct inner 20mm.
Washing machine hoses can vary in terms of length, shape, and material. Some hoses have straight ends, while others have a 90-degree elbow on one end so that the hose fits snugly against your laundry room wall. But they have one thing in common: they all sport ¾-inch female threaded fittings on both ends.
Drain hoses for domestic washing machines and dishwasher's are generally universal but the end fitting that connects to the machine sometimes differ. there are a number of differing “cuff” diameters (19mm and 22mm) but these can often be purchased separately and fitted to a length of hose.
The longer the hose, the heavier the hose. Pressure is not only lost due to length but incline.
The drain pipe should be a minimum of 1-1/2" I.D. (inside diameter) to ensure proper draining. The Washer drain hose is a 1-1/4" O.D. (outside diameter). To be confident that no siphoning of water will take place, the drain plumbing must be a minimum of 30" high for Top Load Washers.
In general, the larger the hose diameter, the more water it can deliver, and the higher the pressure the pressure washer can generate. This is because a larger diameter hose has a larger internal area, allowing more water to flow through at a faster rate.
Hose sizes are designated based on the inner diameter of the hose, which is the measurement of the straight distance between the two furthest points on the inner surface of the tube. Virtually all hoses made globally are made on inch sizes even if given a metric size designation.
Hose Diameter
Because standard household piping is typically ½ inch in diameter, most homeowners only need a standard garden hose size of ½ inch in diameter. A 5/8 inch diameter garden hose size may also work for you, but you'll likely be adding unnecessary weight with this size hose.
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.
FITS ALL WASHERS: 3/4 in. FHT x 3/4 in. FHT: Fits standard washing machine connections. 8 feet Long (96 inches) each hose.
Regardless of their condition, washing machine hoses should be replaced about every 5 years to prevent a flooding emergency. Standard washing machine hoses are made of black rubber. Unfortunately, these hoses only last a few years and will eventually fail, causing one big mess and costly water damage.
The most common size of pressure washer hose, as you shop for 50' hoses, is 3/8". Gas pressure washers pretty much all use 3/8". 5/16" is only a 16th of an inch larger than the standard hose. I would never expect it to make this much of a difference, but it did.
Washing machines all use hoses with 3/4-inch fittings on either end. You should be able to connect any washer hose you purchase to your water supply and to the washing machine, as all parts are standard. You don't have to buy hoses directly from the washing machine's manufacturer.
This drainage hose features one end with a 26mm I.D. elbow, most commonly used at the appliance end to avoid hose kinking. The other end features a 21mm I.D. outlet.
22-30mm Worm Drive Hose Clip / Clamp
This worm drive hose clip is made from steel and adjusts from 22mm to 30mm. This size usually suits washing machine waste hoses.
Garden hoses come in three standard diameters... 1/2”, 5/8”, and 3/4” with 5/8” being your most common type. 3/4” inch is more of a contractor grade hose and 1/2” is the skinny garden hose that is hard to find anymore.
Garden hose fittings let you easily attach to water sources and accessories. Fittings are individual components, while couplings are a pair of fittings. The most common fitting size is 3/4 inch, but 5/8 and 1/2 inch are popular. Hose coupling threads fit tightly together to attach equipment without leaks.
The calculation is as follows: 0.75 inches (3/4) - 0.625 inches (5/8) = 0.125 inches. This means that 3/4 inch is 0.125 inches thicker than 5/8 inch.
