Replacement Actuator Cap for Master Cylinder on a 20004 Dorsey 26' Boat Trailer

Question:

I have a 2004 year Dorsey boat trailer 26 foot cobalt 463 and need an actuator cap for the brake master cylinder. I have the part that screws in but the cap is missing from that. Any ideas? The part that is on has a 3/4 inch threaded plug with a missing cap. The outside is 1in and 5/8 diameter and the inside is 1in Need the cap or a replacement for both

Hey Lisa, thanks for reaching out!

What brand and model actuator do you have? I unfortunately don't have a way to recommend a replacement part without that information.

It is an Atwood actuator

@Lisa Thanks for reaching back out! The Atwood brand was discontinued a while back and there are unfortunately no replacement parts available (I also looked at the other brand replacement caps but none of them matched the specs you gave) so for your application we need to get you setup with a new actuator like the Demco # DM72VR rated for 7K and fits a 2" hitch ball. If you have a different design or need a different weight rating then I'll need to know the model of your Atwood actuator. This can be found either on a sticker or stamped onto the actuator itself.
