Type A Aluminum Camlocks have a male camlock insert on one end, and are female NPT threaded on the other.
Aluminum camlock connectors are among the most widely hose couplings as their light weight, durability and ease of use are advantageous to many users needs. These cam and groove fittings have many uses in the water and wastewater industries and have a working temperature range up to 220°F. They should not be used for pressurized air service.
There is currently no widely used common standard for camlocks in the 1/2", 8" and 10" sizes. All the other sizes are interchangeable and compatible between different manufacturers.
