DL1SPAL Dually Valve Kit Chrome Sprinter 2006-Present 16" Steel Inner/Alum Outer Alcoa Rectangle w/Rounded Edges 3.5"x1.5" Class B or C

Prior to putting these on it was nearly impossible to check or add air to my dually tires. This system makes it a breeze! My application was a 2019 Isata 3 with Alcoa wheels.

Install didn’t go as well as I anticipated. I email Accu Pressure Safety Products LLC thru Amazon’s network. Almost immediately I rec’d an email response with detailed installation steps. I responded with additional questions. Adam called, again almost immediately, and we walked thru the process. Great outcome. I would purchase from Accu Pressure Safety Products LLC again, totally satisfied with my purchase. However, all did not end well. Product had to be modified for my vehicle even though it had standard wheels. Not sure exactly what happened in the two trips to Discount Tire but had to take to the Mercedes dealer to complete the install which cost an additional $400.

The longer extension stems will not seal because of the super thin material that they are made of.Followed the instructions to the manufacturer to the letter and still went through all of the seals.I went back to rubber stems after6 try’s. My wheels are on a 2013 sprinter 3500. Yes I torqued them to specs every time. Save your money!!!

had these for awhile. The inner dually extension works well but the outer 135 bend will not work on my 2015 sprinter chassis with steel rims because the inner round allen end is too large to mount.
