I am going to purchase a TST tire pressure monitoring system for my coach and dinghy. Am considering getting the flow-thru 507. Have not made a final decision as yet. Any advice about whether to get the flow-thru or standard system? Any experiences and /or comments about either of these will be greatly appreciated.

I have the flow through. I would not get the flow through again. It restricts the air flow into the tire too much when airing up your tires. To get any significant air into the tire, you have to remove the sensor anyway.

I have the TST system but did not want the flow-thru. They have the small caps that spin so no one can steal them. I got mine from Mike Benson770-889-9102TSTI gave him the pressure I wanted in all the tires and they came marked where to install and a 3 year warranty. I have the 10 tire setup.JR

I only have the flo-thru type on the rear duelies and I like em there. Very easy to air up & check. They are too long on the front tires and I'm afraid they could hit something like the curb.

We have the non flow thru 507. Very easy to use the tool and remove them. Have 8 sensors for SRW TV and 2 axle 5 ver. Wish I had bought 2 more for spare tires on TV and 5ver. Got ours from rvpartscountry.com and 2 sensors were $64 a year ago. Now over $100 last time I looked. CW is up there in price as well as Amazon now.
