2 Easy Ways To Identify Hydraulic Hose Fittings

Today, most industrial equipment relies on hydraulic systems to properly operate. These machines use adapters and fittings with a variety of thread forms and sealing methods. Unfortunately, all the thread forms look similar, so the different fittings are usually identified by the sealing method used. However, this can be difficult to do when equipment needs to be repaired. Consider the two easiest ways to determine which fitting you have.

1. Determine the Fitting Type

There are only two types of hydraulic Hose fittings Fort Worth TX: reusable and permanent. Reusable fittings are no longer commonly used because they are considered to be outdated technology. You can identify a reusable fitting because it is placed on a hose by using only a vise and a wrench. Reusable fittings typically cost more than permanent fittings as well.

Permanent fittings, also known as crimped hydraulic fittings, are the most popular in the fluid power market because they are easier to attach. However, to attach a permanent fitting, you will need crimping equipment or swaging tools.

2. Identify the Sealing Method

The most common hydraulic fittings you’ll find are mated angle, O-ring and threaded. The mated angle seat fittings have sealing threads that are either straight or parallel. The two mating angle seats form a seal with they are brought together.

There are several types of O-ring designs – boss, flange, seal – but they all have an O-ring seal that creates the closure.

The tapered fittings have either male or female threads. The female threads are on the inside, and the male threads are on the outside. Threading the two together applies pressure on the couplings, thus making a tight seal.

Keeping your industrial equipment running smoothly can be a big task. Being able to accurately and quickly identify which hydraulic hose fittings you need to replace can save time and money.
