The 1 in Fitting Kit Is the Widest Bore in the Line
An AACH50 takes three different fitting sizes, and this is the top of that range. Half-inch, three-quarter and one-inch kits all bolt to the same chiller. The decision is made by the tubing, the pump and the length of the run. One inch is the answer on a big reservoir with a strong pump and a long circuit. Every reduction shows up as head pressure the pump has to overcome. It also covers the AACH50HP, which is easy to miss since both models take the same kit.
Sizing AACH50HP Chiller Fittings Against Your Pump
The rule is simple enough to apply standing at the reservoir. Match the chiller fittings to the narrowest thing already in the loop, and if that is one inch throughout, come to this kit.

FAQ
Can this fitting kit be used with both AACH50 and AACH50HP models?
Yes, this 1 inch fitting kit is compatible with both the AACH50 and AACH50HP chillers.
What is the recommended tubing size when using this kit?
The tubing size should match the narrowest part of your loop. If your system runs one inch throughout, this kit is ideal.
Does this kit reduce head pressure in the system?
No, using a one-inch fitting does not reduce head pressure. In fact, reducing tubing size increases head pressure the pump must overcome.

Installed the 1 inch fitting kit with my AACH50HP and it fits perfectly. The connection is secure and the stainless steel feels durable. Works well with a long loop and strong pump. No leaks after 3 weeks of use.

Used this kit with my AACH50 in a large reservoir setup. The one-inch bore handles the long circuit without pressure drops. Felt like a better match than the half-inch option.

Switched from a three-quarter inch kit to this one-inch version. The system runs smoother now. No issues with leaks or connections. Easy to install and matches the pump well.
