Automatic Air Vent 1/4" NPT

The Caleffi 502620A is a new automatic air vent designed for hydronic heating and cooling circuits. It features a 1/4 inch NPT male connection for direct installation. The brass-bodied valve releases trapped air to maintain system efficiency and prevent noise.

Suits installers needing automatic air removal

This vent suits installers who need reliable automatic air purging on compatible pipework. It is not for systems requiring a different thread standard or connection size. Buyers who need manual operation or a larger capacity vent should look at alternative components.

1/4 inch NPT male thread decides fit

The single specification that decides fit is the 1/4 inch NPT male thread. The valve only seals correctly on matching female ports. Verify the port specification before purchase to ensure compatibility.

Questions about this item

Does the 1/4" NPT male thread on the 502620A match the female port on my RV heating loop?

The 502620A has a 1/4" NPT male connection; verify your system uses a matching 1/4" NPT female fitting before installation.

Will the 502620A vent air from an older brass manifold without corrosion issues?

The 502620A is a new automatic air vent; it releases trapped air from hydronic circuits and its materials are compatible with standard brass and copper components.

How do I confirm the 502620A is purging air correctly after I thread it in?

After installation, watch the vent cap — a steady drip that stops once air is expelled shows the 502620A is seating and venting as designed.
