Hydraulic hose fittings must withstand enormous pressures, so they need to be replaced as soon as they show signs of wear. However, finding the right replacement part can be difficult, especially since fittings may all seem identical to the untrained eye. Below are a few tips for finding the right hose fitting for your equipment.

How to Identify a Hydraulic Hose Fitting

1. Are Fittings Permanent or Reusable?

Permanent fittings are generally more reliable and easy to replace, so they’re more widely used than temporary devices. If the fitting is crimped into place, it’s probably meant to be permanent. Reusable fittings are usually held in place with a nut, which can be removed with a wrench.

2. What Are the Fitting and Port Connections?

Each type of fitting is designed to connect to a particular port and a specific type of hose. For instance, if the port is a metric taper design, the host likely requires a 45⁰ flare fitting. To determine the exact type of ports used in your equipment, you may need to consult your owner’s manual.

3. Look at the Sealing Method

Most hydraulic fittings use one of three common sealing methods. Most will have an O-ring, which consists of a donut-shaped rubber seal inside the connection. Mated angle seals have threats that screw together, creating a tight seal when two angled joints meet. Tapered threads, which feature male and female connections with threads, are generally considered less precise than other sealing methods.

4. Check the Thread Size

Ensuring the threads match is essential for choosing the right hydraulic hose fitting. To accurately check the threads, you’ll need a specialized thread measurement tool, available at most hardware stores. If you’re still not sure, bring the part with you to your supplier, or take high-quality pictures to send to an expert who will be able to find the right fitting for your equipment.
