Compression Ferrule*:

This is the most compact way to attach a 1/2" OD HERMS coil to welded couplings in a HLT when the coil itself is just cut on the ends without a bend to the tangent. It also has uses in a hard plumbed sculpture. When you do the math, this option is only slightly more expensive than a 1/2" NPT elbow and straight compression fitting combination. One end is 1/2" male NPT threads and the other is a compression connection to a 1/2" OD tube.

We offer a choice between stainless and nylon compression rings/sleeves.

  • Stainless Ferrule: This is a set of rings/sleeves/ferrules that slip over the tubing, but behind the compression nut that get squeezed onto the tubing when you lock the nut down TIGHT for the first time. This process permanently crimps the rings to the tubing though you can still remove the compresison nut and tubing (though the nut is now captured). This option is more difficult to use and requires a lot of torque to set, however it is the better mechanical option where a lot of stress is put on the connection.
  • Nylon (AKA Delrin) Sleeve: This option replaces the pair of stainless rings with a one-piece wedge ferrule made of a tough, high temp, food grade plastic. It seals well with minimal tightening on the nut (hand tight plus a quarter turn), never attaches itself to the tubing permanently. Although it is plastic, it does allow for many disconnection cycles without wearing out. The only down side is that it doesn't offer the same mechanical strength as the SS version in cases where a LOT of stress is put on the connection. We recommend this for anything except for mounting HERMS coils where the full weight of the coil is supported by the compression fittings (however we have gotten reports that nylon works OK so give it a try if you want to).

4 of 5 replacement ferrules January 9, 2016
Reviewer: J from Kenosha, WI United States  
I did not receive the exact parts I had originally ordered. I have had contact with purchasing, I'm not sure what actions are being taken. That being said, I have made a few purchases and the previous orders were perfect. I would definitely, and plan to, order from brewhardwarecom in the future. I highly recommend brewhardwarecom for your home brewing needs.

5 of 5 HERMS Coil Life Saver! January 3, 2016
Reviewer: Robert from Charlottesville, VA United States  
After killing a 5ft of steel tubing trying to bend our HERMS coil 90 degrees, I learned about these compression elbows. Without fancy equipment, it was impossible for us to bend tubing at 90 without damage.  These elbows let you connect a your HERMS coil with little equipment to the pot.  True lifesaver! Saved us from having to buy a second coil.  Remember to buy bulkheads with these for HERMS coil so you can go through your pot.
