Belly-band crankcase heaters are one of those parts you don't think about until the compressor struggles to start on a cold morning. The OEM HVAC Compressor Belly-Band Crankcase Heater 240V (part 142-840018-034) is a used Teleflex unit that might be exactly what you need-or a part you should skip, depending on your system and your tolerance for used components.
Quick verdict
If you need a 240V belly-band crankcase heater and prefer OEM parts, this Teleflex unit at $65.00 is worth a close look-provided you're comfortable buying used. It's designed to keep the compressor crankcase warm, which supports reliable starts in cooler conditions. The caveat: it's a used part, and the boat HVAC application mentioned in the description may not match every installation.
Who it suits
This heater fits the shopping moment when you're servicing or replacing a crankcase heater on a 240V HVAC compressor and you want the original-equipment route. The Teleflex branding and OEM label point to a manufacturer-specific part, so it's a good fit for buyers who want a direct match rather than a generic alternative. It also suits anyone working on a marine HVAC system, since the description specifically references a boat application.
What stands out from the listed details
The 240V rating and belly-band design are the two specifications that do the heavy lifting. Belly-band heaters wrap around the compressor body to transfer warmth directly to the crankcase oil, and the 240V rating tells you this is meant for larger systems, not small 120V units. The price sits at $65.00, which is a concrete figure you can weigh against your repair budget. The part number 142-840018-034 gives you something to cross-reference with your existing compressor. The fact that it's used is the most important detail to factor into your decision.
Meaningful trade-offs
The main trade-off is between OEM pedigree and used condition. You get the benefit of a part that's branded Teleflex and described as OEM, which can improve the odds of a correct fit for the right system. But because it's used, you don't get the factory-fresh assurance of a new component. The description points to a boat HVAC application, so this heater is most directly relevant to marine systems. If your setup isn't marine, you'll need to rely on the 240V rating and belly-band format to judge suitability.
