Reduced risk of unexpected failures in the field

HOSE UPGRADES

Upgrade & Repair Your 4-Pressure  Hose

Pivotal Rail Products offers a 4-pressure hose upgrade. This upgrade includes replacing the CBP hose line with a 1/4” ID hydraulic hose line designed for air applications, which also includes the appropriate JIC fittings  to integrate with the pre-existing 4-pressure hose.

Heavy duty hose sleeve, with industrial heat shrink, is applied to the hose to increase durability during use in the field.
