Hydraulic hose fittings slip into 3 major categories. The first type is the Parker 43/71 or Parker 78 series hose fall. These Hannafin style hose fittings are generally styles in a bite to the wire fashion for a robust crimp to the hose. Parker 43/71 styles are commonly used on the subject of the world and are supplied by Parker directly, along behind a few extra vendors in North America, Asia, and Europe. These hydraulic fittings can come in either a carbon steel or stainless steel format. Other mood manufacturers have been hasty to utilize Parker’s dimensions after their dimensional patents expired. Now, these vendors make hose ends that are at least equivalent to Parker. In some cases, the vendors bond real to the indigenous design, but use more material in the production of the hose halt, making it more robust and less prone to failure.
A second major hose type is based occurring for Weatherhead’s “U” series style fitting. These fittings are in addition to definitely common and are referred to as “U” or “V” style fittings. They use less material than the Parker variant and have less of a bite crimp onto the hose but are a fine belittle-cost unconventional, though yet providing the performance required by high pressure hydraulic systems. These hose ends are a particular favorite of OEMs who use demean pressure in their systems.
Splitting the difference amid the Parker and Weatherhead fittings is the third type of hydraulic hose fitting: the Dayco GW, “W” or “Bite-To-The-Wire” style hose fade away. These hose ends are as soon as Parker in that they meet the expense of a deep bite crimp into the rubber hose using steel “fins” inside the ferrule to dig into the rubber hose and “bite” into the steel braid or spiral. The Dayco design has been utterly popular for customers looking to achieve a humiliate-cost of component than Parker’s 43/71/78 series but still require a hermetically sealed bite into the hydraulic hose
Parker, Weatherhead, and Dayco each sell their own crimpers. However Dayco crimpers are unique in that they can crimp any style. Parker crimpers can unaided crimp Parker hydraulic hose fittings and Weatherhead can on your own crimp Weatherhead hydraulic hose fittings. Adjustable crimpers are growing in popularity and meet the expense of leave to enter customers to crimp any and every one hydraulic hose fittings. The largest American manufacturer of malleable crimpers is Indiana-based Custom Crimp.
