We came up with our own in-house version of an insulated glycol tubing set to offer it for a cheaper price than most other name brands.

This one is a BARE BONES version which is just two 7ft lengths of 3/8" ID clear tubing inside closed cell foam insulating tubes (1/4" wall thickness). Most importantly, we've developed a process that allows us to use insulation tubing that has a very tight fit around the inner PVC tubing which helps to keep warm moist room air from getting in and condensing.

The send and return lengths are NOT mated together like the SPIKE brand glycol tubing. You can easily bundle them together as a pair with a few zip ties (we include three for your convenience).

Again, this is the bare bones tubing set. We also offer this set with QDS and TC connections for the Brewbuilt X2 and X3 fermenters as well as a version with pre-terminated push-fit elbows for use with fermenters that have 3/8" top mount cooling coils (such as SPIKE CFs and Temp Twister coils).

Do not exceed 140F temps through the tubing.
