FAQ

What are grease hydraulic fittings?

Grease fittings, also known as Zerks, are a type of hydraulic check valve that can be used for bearings and some internal mechanical parts to provide lubrication.

What are the types of hydraulic grease fitting?

The most commonly used types of hydraulic grease fittings are as follows: push button head grease fittings, push-in grease fittings, pressure relief grease fittings, thread forming grease fittings, and ball type fittings, etc.

What are the uses of hydraulic grease fitting?

Because of its special advantages, the grease fitting can be used in various applications with lubrication and dust protection needs in automotive, industrial, agricultural, aerospace, mining and other fields.

What are the advantages of hydraulic grease fitting?

Grease fitting is also very advantageous because of its special construction. It can stop dust and some other contamination from entering the parts, it can prevent leaks, and it can also provide lubrication.

How many threads of grease fittings?

The most commonly used threads for hydraulic grease fittings are SAE-LT and NPT threads, besides, BSP, BSPT, UNF, metric threads can also be used on grease fittings.

What are the materials of grease fittings?

Hydraulic grease fittings are made of a diverse array of materials, including brass, galvanized steel, stainless steel and more.

How to identify grease fitting thread?

The type of thread is determined by first looking carefully at whether the thread is straight or angled, then measuring the pitch, and finally measuring the diameter of the thread.

How does grease fitting work?

There is a ball check valve inside the hydraulic grease fitting. After the grease enters the fitting, it will generate pressure on the check valve and the ball valve will open to let the grease enter smoothly. After the grease enters, the pressure disappears and the check valve returns to the closed state to prevent fluid flow or contamination from entering.

Can you over grease a grease fitting?

It is best not to use excessive grease. Too much grease can cause temperature imbalance and energy loss in the parts, and it can also damage some of the parts.

How to protect grease fittings?

When using grease fittings, pick standard fittings, use high quality grease, and remember to clean the fittings to prevent dust and other contamination from being pushed into the bearings. If the fittings are damaged, be sure to replace them in time.
