Replacement Tube Bundles

Contact Us

Mainstream offers direct replacement heat exchangers and tube bundles for nearly all major manufacturers. We specialize in cross referencing other manufacturers’ makes and model numbers, thus providing our customers with tube bundles that are of the same (or greater) quality than the original, while simultaneously matching the dimensions and performance of your existing unit.

Cross-Referencing Model#s

Just send us a picture of the nameplate on the heat exchanger or water heater, and we typically will have enough information to put together a quote.

Lead Times

The standard lead times for tube bundles is 2 – 3 weeks, but expedites are nearly always available. In some cases, as fast as 24 hours is achievable.

High-Quality Materials

Steel, copper, brass, stainless steel, cupro-nickel, etc. Let us know if you would like an upgrade over the existing design.
