201430 - Miller 36-Inch Coolant Hose LH Thread to Quick Connect

Genuine Miller Coolant Hose Assembly for Industrial Welding Systems

The Miller 201430 Hose Assembly is a specialized component designed for the rigorous demands of industrial welding cooling systems. As an Original Equipment Manufacturer (OEM) part, it guarantees precise fitment and performance standards consistent with Miller Electric's renowned quality. This assembly functions as a critical conduit for transferring coolant between the cooling unit (such as a Coolmate system) and the welding torch or power source interface. Maintaining the integrity of the cooling loop is essential for preventing overheating in high-amperage TIG and MIG applications, and this hose is engineered to deliver reliable flow without leakage.

Technically, the assembly measures 36 inches in length, providing sufficient reach for standard machine configurations without creating excessive slack that could become a tripping hazard or prone to snagging. The hose is terminated with two distinct connection types: a Left-Hand (LH) thread and a Quick Connect fitting. The utilization of a Left-Hand thread is a standard safety convention in the welding industry for water/coolant lines, physically preventing the accidental connection of liquid lines to gas regulators or flowmeters, which typically employ Right-Hand threads. The Quick Connect end allows for rapid integration with compatible Miller receptacles, streamlining maintenance procedures and setup times.

Constructed from durable materials compatible with standard welding coolants (such as ethylene glycol mixtures or deionized water blends), the hose resists degradation from chemical exposure and environmental factors common in fabrication shops. The crimped ferrules at both ends ensure high-pressure retention, mitigating the risk of catastrophic failure during operation. For maintenance, repair, and operations (MRO) professionals, utilizing genuine Miller replacement parts like the 201430 ensures that the thermal management specifications of the welding equipment are upheld, thereby protecting the longevity of expensive torches and power sources.
