Hydraulic hose fittings belong to 3 significant categories. The initial type may be the Parker 43/71 or Parker 78 collection hose end. These Hannafin type line accessories are generally models in a mouthful to the wire style for an effective crimp to the hose. Parker 43/71 designs are generally used all over the world and are furnished by Parker straight, along with a few other companies in North America, Asia, and Europe. These hydraulic accessories may come in either a carbon material or stainless format. Other quality suppliers have already been quick to make use of Parker's proportions after their dimensional patents expired. Now, these sellers produce line stops that are at the very least equal to Parker. Sometimes, the companies maintain correct to the original design, but use more product in the creation of the line conclusion, making it better quality and less prone to failure.

Another major line form is based upon Weatherhead's "U" series fashion fitting. These fittings are also really frequent and are referred to as "U" or "V" design fittings. They use less substance than the Parker alternative and have less of a bite crimp onto the hose but are a good lower-cost option, while however providing the performance needed by high stress hydraulic systems. These line stops certainly are a particular favorite of OEMs who use decrease stress inside their systems.

Breaking the huge difference between the Parker and Weatherhead fixtures is the 3rd type of hydraulic hose fitting: the Dayco GW, "W" or "Bite-To-The-Wire" fashion hose end. These line ends are much like Parker because they give a deep bite crimp into the plastic line using metal "fins" in the ferrule to dig in to the plastic line and "bite" to the steel braid or spiral. The Dayco style has been extremely popular for consumers looking to achieve a lower-cost of portion than Parker's 43/71/78 series but still need a powerful bite into the hydraulic line شیلنگ هیدرولیک

Parker, Weatherhead, and Dayco each sell their very own crimpers. Nevertheless Dayco crimpers are special in that they'll crimp any style. Parker crimpers can only crimp Parker hydraulic hose fittings and Weatherhead can only just crimp Weatherhead hydraulic line fittings.
