5-Gauge Hydraulic Pressure Test Kit with 5 Hoses, 13 Couplings and 14 Tee Connectors

Common Uses

• Slow hydraulics, weak lift force, drifting cylinders, overheating oil, or a suspected relief-valve or pump problem calls for measured pressure—not parts swapping.
• The five gauges, hoses, couplings, and tee connectors let a technician compare pressure at multiple points and narrow a fault to the pump, valve, circuit, or actuator.
• Replacing an original hydraulic pressure test kit that is worn, damaged, missing, contaminated, or no longer operating correctly
• Completing a repair after confirming the related wiring, fuel, mechanical, mounting, hydraulic, exhaust, cooling, or structural system is serviceable

Technical Specifications

• Product Type: Hydraulic pressure diagnostic kit
• Gauge Ranges: 10, 100, 250, 400 and 600 bar
• Hoses: 5
• Couplings: 13
• Tee Connectors: 14

Installation & Fitment

• Use the machine service manual to identify the correct test point and expected pressure
• Depressurize the circuit before connecting or disconnecting a hose
• Start with a gauge safely above the expected pressure
• Keep hoses clear of pinch points and never search for a leak with bare hands

Compatibility Notice

Confirm the machine test-port thread, coupling profile, expected working pressure, and service-manual test procedure; equipment brand alone does not guarantee adapter fit. Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown. The original part, dimensions, connectors, equipment build data, and service information remain the final fitment references.

Frequently Asked Questions

Q: What problem can lead to replacement of this hydraulic pressure test kit? A: Slow hydraulics, weak lift force, drifting cylinders, overheating oil, or a suspected relief-valve or pump problem calls for measured pressure—not parts swapping.

Q: Which models or applications are listed as compatible? A: It is listed for Caterpillar construction equipment using a matching test-port adapter; Case construction equipment using a matching test-port adapter; John Deere construction equipment using a matching test-port adapter; Komatsu construction equipment using a matching test-port adapter; Other hydraulic machinery with matching couplings and pressure ranges. Confirm the machine test-port thread, coupling profile, expected working pressure, and service-manual test procedure; equipment brand alone does not guarantee adapter fit.

Q: How do I confirm this is the correct replacement? A: Confirm the machine test-port thread, coupling profile, expected working pressure, and service-manual test procedure; equipment brand alone does not guarantee adapter fit.

Q: Is this an original equipment manufacturer part? A: No. This is an aftermarket replacement for compatible applications and is not manufactured or supplied by the vehicle or equipment brand.

Q: What should be checked before installation? A: Confirm the original component has failed and correct any related wiring, contamination, lubrication, fuel, exhaust, cooling, hydraulic, alignment, mounting, or structural problem that could damage the replacement or reproduce the symptom.
