Choosing the Right Hydraulic Hose for Your Needs

Choosing the Right Hydraulic Hose for Your Needs

You might be an expert contractor, knowing your tractor inside out, but how far does your experience and knowledge reach with hoses, hose sales, and even hydraulic hose repair? Not everyone is an expert in this field, and it can take expert assistance or a bit of knowledge to nail down those finer points.

If you are in the market for a new hydraulic hose after your hydraulic hose repairs failed, then read on. Here are some helpful hints for how to read and understand the “STAMP” acronym for hose selection.

S – Size

The most obvious and important factor in choosing the correct hydraulic hose is the size. Failure to get the right size can result in incorrect flow velocity. If the hose flow is too slow, you experience a sluggish and ill-performing machine. If it’s too high, you can experience pressure drops which damage the hose system and cause it to leak. You’ll then need to carry out hydraulic hose repair which can cost time and money.

To identify your hose fitting for replacement, refer to the dash numbers and sizes. The dash number is the inner diameter of your hose, measured in sixteenths of an inch. If you are unsure what your hydraulic hose sizing is, check the layline.

Unfortunately, with age and wear, the printing of this sizing can wear off. In that case, you have to measure your assembly length and fit before you cut the hose and measure the inside diameter.

T – Temperature

If hydraulic hose repairs have failed, and you now have to buy a new hose, then the second letter of STAMP is as essential as the first. T, or temperature, refers to both the ambient and media temperature of your hose. Ambient is where the hose is in use, and media is through the hose itself.

The goal of considering the hydraulic hose temperature is to ensure the one you buy meets or exceeds the highest temperature you will run on your machine at any given time. Various fluids also run at different temperatures, so make sure you factor this in when you are buying a new hose for your machine.

A – Application

The key to a long-lasting and well-performing hydraulic hose is ensuring you buy it for the right application. Failure to consider this when buying a hose can result in premature failure and costly damage.

Before you swipe your credit card, ask yourself a few questions:

  1. What am I using the hose on?

  2. Is the routing confined?

  3. Will there be any abrasion?

  4. What will the hose be exposed to?

  5. Will I need to use field-attachable fittings?

Every hydraulic hose is different for various applications, which you’ll discover as you carry out yet another hydraulic hose repair. You would buy a hose with a tough cover for an abrasive surface, and bendable hoses for tight spaces. Always factor in the environment and circumstances before you buy your new hydraulic hose.

M – Media

The media, or media velocity, is a crucial consideration if you want to avoid costly hydraulic hose repairs on your new or existing hose. Your hose must be compatible with the medium you are conveying. The compatibility must be precise for the inner tube, O-rings, hose fittings, and the cover as well.

P – Pressure

One of the first things you need to look for on a new hydraulic hose is the information about the pressure. You need to know the system working pressure, the pressure of any spikes, and surge pressure as well.

The best hydraulic hose for your needs is one that has a maximum working pressure at least equal or greater to the very highest of your machine – including those surges and spikes. It should also meet industry specifications.

What about STAMPED?

Sometimes, you may see STAMPED rather than STAMP when referring to hydraulic hosing. The E and D refer to environmental factors and delivery. The more common acronym, however, is STAMP.


A common mistake that many contractors make is that they buy the most affordable hose to save themselves money. While there is nothing wrong with getting a bargain, a cheap and poorly manufactured hose can equate to hydraulic hose repairs you possibly didn’t anticipate. Not every hose is going to suit your application, which is why it’s crucial to rely on STAMP to make your decision instead of the price tag.


The size, temperature, application, media, and pressure of hydraulic hoses all matter when you are buying one for your machinery. Hydraulic hose repairs can only take you so far before you need to look at a brand new setup. Factor in the very highest pressures and temperatures, consult an expert for help, and you can enjoy a seamless purchasing and installing process for your new hydraulic hose.
