Thanks perfect fit. Appreciate timely processing of the order.


ETrailer sent this cap because the one that came with my master cylinder was not seating properly. Once I informed them, they sent this one quickly and it works perfectly!

Works Great
David E - 09/01/2017


Recently ordered and received a new trailer coupler from etrailer, the order was processed and shipped in a very timely manner. Although the coupler was packaged very well, it managed to receive a crushing blow to the filler cap. Close review showed it was fractured and had a split gasket. It only took one email for a rapid response and a replacement to be on it's way.
This is my third parts order from etrailer, pricing, packaging and delivery have always been first class and much appreciated.


Looks great but has not been installed yet

  • If the Replacement Cap # T1755600 Becomes Distorted Will it Still Fit and Allow Brakes to Work
    Unless the threads of the part of the actuator that the Replacement Cap # T1755600 screws onto (see attached picture) is damaged then the diaphragm type replacement cap will fit just fine. If the cap itself becomes distorted somehow then you might have some difficulty installing it, but if it can be installed correctly then your brake system should still work. If it is damaged to the point that it does not provide a good seal then it will cause problems. It doesn't necessarily come with...

  • Replacement Master Cylinder Caps for Titan Brake Actuating Trailer Couplers
    There are a few different replacement caps for the various Titan actuators. Replacement # T4830601 that you referenced fits model 10 and 20 actuators. Since it doesn't fit you must have one of the others. Cap # T4480701 is for model 60 and Aero 7500 actuators. It has an overall width of 1-1/2 inches. The threaded part that screws in is 1-1/4 inches. And then there is # T1755600 for model 6 actuators. It is pretty unique compared to the others since it screws around the mating part of...

  • Locating Replacement Cap for Master Cylinder on Vantage Boat Trailer
    We do have a nice selection of replacement master cylinder caps available. I recommend first checking to see if you can find a manufacturer or part number somewhere on the master cylinder to better help locate the correct replacement. The closest cap we have available to the 3 inch dimension you provided is the Replacement Cap # T1755600. I went out to our warehouse and measured an overall outside diameter on the cap of just over 3 inches (3-1/8 inches to be exact). This diaphragm type...

  • Master Cylinder Replacements for Titan Actuators
    I was unable to find an order number for you so I'm not entirely sure what you have, but were you referring to the Replacement Master Cylinder Cap with Diaphragm for Titan Model 10 and 20 Brake Actuators # T4830601? I only ask because there is not a model 0100, but there is a Model 10 such as part # T2477600. A master cylinder cap will only fit the direct model it is designed for so you will need to know your actuator's model in order to get the correct cap. The Replacement Cap for...
