Hydraulic Hose
Labrie Enviroquip Group uses premium quality hydraulic hose designed specifically for use in our
hydraulic systems. All pressure hoses have a maximum working pressure of at least 3000 psi, with a x4
burst pressure rating. The hydraulic hose type is identified on the hose covers, in the “lay line”. When
replacing any hydraulic hose, it is extremely important that the replacement hose carries the same
SAE rating as the original hose.
Hose types are listed by a designation or number set by a regulatory authority such as ISO and the
SAE (Society of Automotive Engineers). These regulatory bodies set standards in the hydraulic hose
industry.

Inspect all hydraulic hoses and tubing daily for abrasion, cuts, cracks and damage. Replace any
hydraulic hose which shows signs of damage.
