Product Overview
Enlarger cuff. It threads onto 1.5 inch (38mm) vacuum hose and slips onto a 2 inch tool.
Use it when you have a 1.5 inch hose set and need to run a 2 inch tool on the end of it.
Important — AH46 and AH48 Are Easy to Transpose
Both parts are "1.5 inch and 2 inch", and they do opposite jobs. The question that decides it is: what size is your hose?
- Hose Cuff 1.5 Inch Hose to 2 Inch Tool (AH46) — threads onto 1.5 inch hose, slips onto a 2 inch tool. The enlarger.
- Hose Cuff 2 Inch Hose to 1.5 Inch Tool (AH48) — threads onto 2 inch hose, slips onto a 1.5 inch tool. The reducer.
Order by the hose, not by the tool, and you will get it right every time.
Thread and Slip — Not Male and Female
Standard vacuum hose cuffs are specified as thread x slip, and getting this straight removes most of the confusion in this part of the catalogue.
- The threaded end screws onto the vacuum hose. It engages the external helix of the hose itself, which is why it grips.
- The slip end is a plain socket that pushes onto the wand or tool tube.
There is no male or female option on a standard screw cuff. That terminology belongs to the Flash Cuff quick-connect range, which is a different and non-interchangeable system. If someone has told you to order a "female 1.5 inch cuff", they most likely mean a Flash Cuff.
Worth knowing: there is no published thread standard, pitch or TPI for vacuum cuff threads, from any manufacturer we can find. The pitch is set by the helix of the hose, not by a fitting standard. Cuffs from different makers usually interchange, but test the joint before you rely on it.

Frequently Asked Questions
Which size is the hose?
1.5 inch. If your hose is 2 inch you want AH48 instead.
Does it reduce airflow?
Any change of section costs a little airflow. Running a 2 inch tool on 1.5 inch hose is limited by the hose, not by this cuff.
Is it male or female?
Neither — thread and slip. See the note above.

What We See in the Field
When vacuum fades gradually, check the cuffs, hose ends and joins before blaming the blower or vacuum motors. If the hose end is stretched or cracked, cut it back to sound material before fitting the new cuff.
