What Are the Thread Sizes of the Orifice Connector for Trailer Brake Actuators

Question:

Orifice Connector for Dico Trailer Brake Actuators - 1/2inch Male to 3/8inch Female Titan Accessories and Parts Code: T1209800 Above is how the part is listed and has the dimensions needed if actual ruler measurements and brass pipe threading - not flare etc. However, in the description that follows == it says 3/16ths female. There is quite a difference in size then. We are trying to find an orifice for an older Loadmaster Trailer where the orifice needs to be replaced to the brake actuator master cylinder connection. Im away from the actual trailer and did not get the model of the actuator - so am going by the actual ruler measurements. So, first need to confirm male and female end measurements - and then the next question is on the orifice itself. How much will that matter? The one we have that is broken has a slightly larger orifice. Thanks

The thread size is 3/8"-24 but the fitting size is 3/16". This standard for trailer brake lines. This will go from 1/2 inch thread size to 3/8 inch.

If the dimensions you took are 1/2 inch and 3/8 inch of the threads this will fit.
