Fittings Basics

Hydraulic hoses can be unique, like your business. Here are some things you should know if the fittings of your hoses are also unique.

Hydraulic fittings are metal parts that join things together, and, as such, they have to meet exacting standards. They have to work with the particular temperature, fluid, and pressure that the hose experiences. There are many types of fittings.

1. Compression fittings that use rings, gaskets, or ferrules to attach a hose to the vessel.

2. Flare fittings that have ends shaped like cones or flares and have the vessel inserted in it.

3. End fittings that can come in two varieties: clamp end fittings and plain fittings.

4. Threaded fittings, which have metal grooves around them called threads.

Threaded fittings are pretty common. They come in male and female types that can be screwed together provided the threads are the same size. However, it gets tricky because thread size can vary wildly. JIC, JIS, AN and BSP fittings are all threaded, but they have different seat shapes and thread sizes.

This doesn’t cover all the many functions and shapes that a fitting can have. There are fittings for capping or plugging a hose and there are fittings for joining more than two hoses together. There are T-shaped fittings and connectors.

Fitting Sizing

Hoses are measured for the inside diameter (ID) and the outside diameter (OD) in order to figure out the size appropriate for your fitting. These measurements can be given in millimeters (using the metric system) or in inches. The SAE J516 lists standard sizes, but you don’t always get to use a standard size.

When Do You Need Customized Fittings?

Businesses acquire their equipment in many ways. Sometimes you inherit an old hose that works fine, but whose parts have long since disappeared from the market. Other times, the hose has to be made from scratch to begin with because your business has an unusual requirement. Perhaps it needs to be particularly long or wide in order to handle the load. The fittings can differ from the standard type of fitting in size, shape, thread size, and in how many hoses it connects.

It’s important to match the old fitting exactly. Both the safety of your employees and the functioning of the hose depend on it. Hose fittings are subjected to lots of pressure, which means that poorly made or fitted parts can be blown off at high velocity, causing the hose to whip around. Also, many types of liquids are pumped through hydraulic hoses. This creates a mess and risks injuring people.

Custom Hose Delivers

When someone needs a part they can’t buy as-is, they will want assurance that the part will do the job well and for a long time. Custom Hose makes a point of making them with precision machining and brazing them with silver. This brazing process heats a filler at temperatures higher than 450 degrees Fahrenheit (ca. 232 °C) to join metal pieces of your fitting. Brazing covers fine gaps and creates a tight fit between metal parts, ensuring that the fitting is durable.

Custom Hose will use a customer’s original part to create a fitting that matches the machinery exactly. If we can find new parts to work with, we will so that your business gets hoses that can handle whatever high-pressure application you put them to.
