Coolant - Flood Coolant Hose - 35' Universal Replacement - Introduction

The Flood Coolant 35' Universal Replacement Hose is a universal kit. Not all of the parts will be used.
  • This kit contains all of the parts necessary to replace the low-pressure supply hose on a Haas CNC machine.
  • The hose in this kit replaces the 5/8" or 3/4" flood coolant, factory-crimped hose on your machine.
  • The clamp-style hose fittings make a tighter connection that resists leakage.
  • The nylon braided hose is durable, providing years of standard use.
Safety Notes
Caution: When you do maintenance or repair on CNC machines and their components, you must always follow basic safety precautions. This decreases the risk of injury and mechanical damage.

Do these steps before you do work in the machine or in the control cabinet:
  • Set the main circuit breaker to the OFF position.
  • Use an approved lock with an approved safety tag. Always follow lock-out procedures in accordance to local government rules.
  • After turning off the machine, wait at least 5 minutes before working in the control cabinet, to allow power to dissipate. Wait for the voltage indicator LED on the vector drive to go off completely.
  • Always turn off the main air supply when you work on any part of the pneumatic system.
  • Make sure to rest the spindle head on a block of wood when work is done on a vertical axis. This will prevent any unintended movement that could result in the axis falling.
  • Never alter any safety circuits on the machine.
You should not do machine repair or service procedures unless you are qualified and knowledgeable about the processes. Serious damage to the machine components can result in costly repairs. The service technicians at your Haas Factory Outlet (HFO) have the training and experience, and are certified to do these tasks safely and correctly. The repair and service work performed by your HFO is protected with a limited warranty.
danger: Some service procedures can be dangerous or life-threatening. DO NOT attempt a procedure that you do not fully understand. If you have any doubts about doing a procedure contact your Haas Factory Outlet (HFO) and schedule a service visit.

Coolant - Flood Coolant Hose - 35' Universal Replacement

Step 1

Prepare the new hose:
  • Remove the old coolant hose from the machine.
  • Cut the new coolant hose to the same length as the old hose.
Select new fittings:
  • Remove the old fittings from the machine, if applicable.
  • Match the fittings from the old hose and the machine, if applicable, to the fittings in the kit.

Step 2

Install the new BARB FITTING [D,E, or F] onto the machine.

Put a HOSE CAP [A] over the barb of the fitting.

Put a CLAMP [B] over the end of the new HOSE [C]. Push the new hose fully onto the fitting.

Put the CLAMP [B] back over the barb section of the fitting 1/4" - 3/8" (6-10 mm) from the cap.

Use clamp pliers [5] to tighten the clamp around the hose.

Do this again on the other end of the hose.

Operate the coolant system at full pressure. Look for leaks.
