This is the ultimate guide to the hydraulic suction hose.

In this all-new guide, you will get everything basically important about the hydraulic suction hose.

Let’s get started!

What Is Hydraulic Suction Hose?

Here are various types of hydraulic hoses sold in the hydraulic industry, and SAE 100R4 is designed as the hydraulic suction hose.

Compared with other hydraulic hoses, SAE 100R4 hydraulic suction hose is designed differently, with the stainless steel wire is embedded in the reinforced layer.

This is the structure of the hydraulic suction hose.

Tube: Oil resistant synthetic rubber (same with other hydraulic hoses)

Reinforcement: High tensile cords and helix steel wire (the helix steel wire is specially designed for hydraulic suction & discharge hose)

Cover: Oil and weather resistant synthetic rubber (same with other hydraulic hoses)

What Is Hydraulic Suction Hose Used for?

The hydraulic suction hose is designed with a hard outer cover, and it can be used for hydraulic fluid (except ester-based oil) suction and conveying.

The hydraulic suction hose is frequently applied to suction & discharge, anti-static delivery hydraulic line, and vacuum applications for petroleum-based and water-based hydraulic fluids.

SAE 100R4 is the hydraulic suction hose, it is designed to be a textile reinforced hydraulic hose. You can see that the reinforcement of the hydraulic suction hose consists of the spiral steel wire. 

The inner tube of this suction hose hydraulic hose is manufactured with the Nitrile rubber material, which has excellent oil resistance so that you can apply this suction hydraulic hose to convey all oil-based, petroleum-based hydraulic fluids. And the inner tube can’t be corroded due to the Nitrile rubber performance.

The hydraulic suction hose should work under high pressure, so that the reinforced layer is designed with the spiral steel wire,  to add much strength making it durable and stable during its service life.
