Ldi Industries AV104 Protected Vent Aluminum Threaded

Product Description

The LDI INDUSTRIES AV104 is a threaded aluminum protected vent designed to allow controlled airflow while preventing debris, insects, and contaminants from entering enclosed equipment, tanks, or housings. Featuring a 1/2-inch threaded connection and a 1-1/4-inch hex flats diameter, the AV104 installs quickly using standard hand tools. Standing 1-5/16 inches tall, this compact vent suits applications where space is limited but reliable venting is required. The all-aluminum construction resists corrosion and keeps weight low. Licensed trades and maintenance technicians working on fluid systems, enclosures, and storage equipment commonly install this type of fitting.

The AV104 is suited for residential and light commercial applications where venting of tanks, reservoirs, gear housings, or enclosed systems is necessary. The threaded connection style allows direct installation into standard tapped ports. Its protected design shields the vent opening from direct splash, particulate intrusion, and small debris, making it appropriate for both indoor and outdoor installations where environmental exposure is a concern.

Key Features

• 1/2-inch threaded connection for direct installation into standard tapped ports

Compatibility

Designed as an OEM-style replacement or direct-install protected vent for equipment with standard 1/2-inch threaded vent ports on tanks, reservoirs, or enclosed housings.

Installation Notes

Installation is performed by the appropriate licensed trade depending on the system type, such as a plumber, mechanic, or equipment technician. Thread the AV104 into the tapped port by hand first to confirm proper thread engagement before applying wrench torque. Depressurize and drain the relevant system or enclosure before removing any existing vent fitting. Apply thread sealant appropriate for the fluid or gas service if required by the application or applicable code.
