KMC Controls HFO-0028 Tube Assembly

For veteran contractors servicing legacy pneumatic systems, the KMC Controls HFO-0028 Tube Assembly is a critical replacement component designed to maintain the integrity of pneumatic control loops. This 10-pack of 8-inch assemblies is specifically engineered for high-reliability connections between pneumatic thermostats, receiver-controllers, and damper actuators. Each HFO-0028 tubing kit comes complete with four durable eyelets and two tension springs, ensuring a secure, leak-proof interface that resists the vibration and mechanical stress common in air handling units.

When you are troubleshooting HVAC airflow control issues or performing routine maintenance on KMC pneumatic systems, replacing brittle or discolored lines with these OEM tube assemblies prevents localized pressure drops that can lead to calibration drift. The 5/32" outer diameter tubing is optimized for standard pneumatic fittings, providing the consistent signal response required for precise proportional control. These assemblies are essential for technicians who need to restore HVAC pressure regulation to original manufacturer specifications without resorting to Field-rigged solutions that compromise system stability.

• Precision Reliability: Includes four industrial eyelets and two springs per assembly to ensure robust mechanical connections in pneumatic control sequences.
• Bulk Efficiency: Supplied in a 10-pack (10PK) to provide technicians with ready inventory for multi-zone HVAC service sets.
• Signal Integrity: 8-inch pre-cut tubing reduces installation time and minimizes the risk of kinks that cause pneumatc signal latency.
• OEM Compatibility: Designed specifically as an HFO-0028 replacement part for seamless integration with existing KMC Controls hardware.

What components are included in each individual tube assembly?
Each of the ten assemblies in the pack features an 8-inch tube, four eyelets for secure mounting, and two springs to maintain tension and prevent line sagging during operation.

Can this assembly be used with other pneumatic brands?
While designed for KMC Controls, this HFO-0028 kit is compatible with most standard 5/32" pneumatic systems where an 8-inch jumper or connection lead is required.

When should these tube assemblies be replaced during maintenance?
Technicians should replace these leads if the tubing appears brittle, shows signs of micro-cracking, or if the eyelets no longer provide a snug fit, as these issues lead to pneumatic leaks and system inefficiency.
