Hydraulic application caps and plugs provide the critical role of protecting hydraulic systems from dirt, moisture, corrosion and damage during manufacturing, transit, shipping and storage. All of which can be harmful factors contributing to hydraulic system failure. Hydraulic caps and hydraulic hose plugs should be used through various processes such as manufacturing – particularly in powder coating and painting, during assembly and packaging and also used during machine shutdown when undertaking routine maintenance or repair. Their job is to prevent all types of contaminant from entering hydraulic systems through ports and fittings. Our range includes various thread types such as UNF, BSP, metric and JIC threads and many more dependent on application requirement.
