Frequently Asked Questions (FAQs)

1. What are the different types of hydraulic couplings?

There are three common types of hydraulic couplings: thread interface, mated angle, and O-ring. These different coupling interfaces are used in hydraulic systems for various applications and connections.

2. What does a hydraulic coupler do?

A hydraulic coupler enables quick connections to a hydraulic system. It consists of male and female halves that can be easily connected by hand. For example, the C-Series Coupler is a standard hydraulic coupler used in many Enerpac pumps and cylinders up to 10,000 psi (700 bar).

3. What are the most common hydraulic fittings?

The most common hydraulic fittings include O-ring, mated angle, and tapered thread connectors. These fittings are widely used in hydraulic systems, although there are other types available for specific applications and requirements.

4. Why do hydraulic couplings leak?

Hydraulic couplings may leak if the nut is not properly tightened. Over-tightening can also damage the fitting integrity and cause leaks. It is important to ensure that the nut is tightened correctly to prevent fluid leaks in hydraulic systems.
