Hayden Discharge Adapter - ...
$6.99
Product details
Part 762027 is a discharge adapter that steps standard 2-inch central vacuum pipe down to 1-7/8 inch, sized for the exhaust connection on Hayden and Canplas power units. It is the fitting used at the discharge side of the system, where the last run of pipe needs to mate with the exhaust port on the unit itself rather than with another inlet or trunk line elsewhere in the house.
The seal at the discharge fitting matters as much as any seal at an inlet, even though no one ever plugs a hose in at that end. A loose or undersized adapter here lets exhaust air and fine dust escape into the utility space near the power unit instead of routing fully outside or through the muffler, and it bleeds off pressure the system needs to move air efficiently from every inlet down the line.
If your system runs Hayden equipment, or a Canplas power unit sharing this exhaust sizing, check the fitting dimensions on your existing discharge connection against 2 inch to 1-7/8 inch before ordering, since exhaust ports are not universal across every brand of power unit on the market.
- Part: 762027
- Reduces: 2 inch to 1-7/8 inch
- Fits: Hayden and Canplas central vacuum power units
- Location: discharge/exhaust side connection
Pair it with a muffler on the downstream side if the goal is a quieter exhaust as well as a properly sized connection at the power unit. Fitting the adapter correctly the first time saves a return trip later, since exhaust-side leaks are often mistaken for a struggling motor rather than an air leak.
