Minnesota Hydraulic Hose Caps & Mobile Hydraulic Hose Replacement

Industries need many types of hose accessories and hose fittings in order to function, and it is more cost-effective to prolong the working lives of all these pieces of equipment. A good way to do that is to keep a hose in good condition. One accessory that helps you do that is the hydraulic hose cap.

Keeping a hose clear of debris and the ends pristine is very important, especially when they are being transported between jobs or being stored. After all, you don’t want your hose malfunctioning before you are ready to replace it. This can happen if foreign particles in the air get into an uncapped hose to wear down the materials prematurely. Hose caps are a way of protecting the interior of a hose from contaminants and the other hydraulic parts from damage.

Hose caps have a female-threaded end that screws into male-threaded hose end, and they cover the openings with hexagonal-shaped heads.

They are often sold in cap-and-plug kits, since plugs serve a similar purpose. Plugs, however, have a male thread and a range of head shapes, including countersunk and square. They look a little like screwed-in nuts and bolts, while caps resemble hats.

People normally make caps out of steel or stainless steel.

Considerations

The caps only seal the end of a hose if it is compatible with the type of hose and be the same size as the ends. The size can be anywhere from 1/16 inch to 2 inches. Another factor in whether a cap will fit your hose is what type of fitting it has. There are several types to choose from.

JIC fittings are a standard type defined by the SAE as a fitting that has been machined with a 37-degree flared surface. (The flare refers to a type of compression fitting used on metals such as steel.) Caps with this type of fitting are good for high-pressure applications and can work for hoses designed to deal with pressure up to 1250 psi.

ORFS fittings have a flat face contact surface. They can work for up to 3000 psi, and have an o-ring.

KOMATSU fittings are machined with a 30 degree flare.

JIS fittings have a 30 degree flare seating surface.

There are also DIN, BSPP, and FLANGE fittings for caps. These have different threads and surfaces. This means that each cap fitting will need to be matched exactly to their hose fittings.

The SAE J1273 stresses making sure fittings are compatible in order to keep hose safe to use. This prevents blowouts and premature breakdown.
