Choosing an AACH25HP Chiller Fitting Kit by Tubing Size
The question comes up constantly and the answer is that you choose. Active Aqua sells the AACH25, AACH25HP, AACH50 and AACH50HP fitting kit in two sizes, and this is the half-inch one. Match it to the tubing already in the loop rather than to the chiller, because the chiller accepts either. Half-inch is the common choice on reservoirs under a few hundred gallons where the pump is modest and the run is short. Above that, or on a long run, three-quarter is usually the better call and there is a kit for that too.
What the 1/2 in Chiller Fittings Kit Contains
Two barbed fittings, two hose clamps, one replacement fuse and two rubber collars for the inlet and outlet. Treat it as the standard component set for connecting the chiller to your system.
| Component | Quantity |
|---|---|
| Barbed Fittings | 2 |
| Hose Clamps | 2 |
| Replacement Fuse | 1 |
| Rubber Collars | 2 |
FAQ
What tubing size does the AACH25HP fitting kit support?
The AACH25HP fitting kit supports 1/2 inch tubing. It is designed to match the existing tubing in your loop, not the chiller itself.
Is the replacement fuse included in the kit?
Yes, one replacement fuse is included in the 1/2 inch chiller fitting kit.
Can this kit be used with a three-quarter inch tubing system?
No, this is a 1/2 inch fitting kit. For three-quarter inch tubing, a separate AACH50 or AACH50HP kit is required.

Installed the AACH25HP kit on my 300-gallon reservoir. The fittings connected smoothly and the rubber collars kept the hose secure. The replacement fuse was easy to find and replace when needed. Works well with my standard pump setup.

Fits perfectly with my existing 1/2 inch tubing. The hose clamps are sturdy and the barbed fittings don’t leak after a few weeks of use. Good value for the included fuse and collars.
