Funding complete for new valve-stem cap with visual pressure indicator

| February 25, 2014

RightPSI 2012 production versionThe folks at RightPSI have built a new valve-stem cap made in the U.S.A. and matched to desired tire pressure to give a visual indication when pressure is low or high. At 20 percent low, the otherwise black stem shows a bright orange. If overfilled, the color shows yellow. The caps are entirely mechanical, the company notes. 

They’ve had a Kickstarter crowd-funding campaign ongoing since Feb. 15 now, and in no time they’ve met their initial goal of $20,000 for start-up — by a long shot. The company’s well over $30,000 raised, and those interested in trying the product out have another month or so to pledge to the funding campaign.

It’s no surprise, perhaps, given that RightPSI received the Popular Mechanics Editors Choice Award for Outstanding Achievement in New Product Design & Innovation, and it was an MSN Top Pick from the SEMA show. It’s begun marketing the product to truckers, too, as you’ll see in latter portions of the video below. 

Rewards for contributions to the funding campaign, mostly, are sample packs of the caps, at least one or two of them big enough to outfit a tractor-trailer in total. For all campaign contributors, the company has pledged to reach out about your desired PSI rating before sending the caps. Though when the product initially makes its way to stores, they’ll be putting out a “standard range of PSIs” of  28, 30, 33, 35 and 40, “we can make the caps to apply to any tire pressure that is commonly used,” says rep Jack Zampolin.  

You can pledge, and find out more information, via their Kickstarter funding page here.

    Are they easily removed? In other words, are they easily stolen off of our equipment? Sad it is like that now a days that one has to ask.

    Camping World has had something like this for years. But theirs were not “flow through”. Think it was called TireMinder. (not sure). And you are correct in asking how easy they are to steal. And yes–it’s to bad ya gotta ask.

    I looked at those for our motor home… What ever happened to the “Cat Eyes” that used to be around years ago? I liked those, but rarely see them.

    I need a product that gives accurate information; tire pressure loss is +/- 1.5 lbs. Having lost twenty lbs. of air & then The Product indicates low tire air pressure…is a problem.

    Sad when this question has to be asked.
    why can’t people just leave stuff alone?

  • norman ott

    I have some of them from 30 years ago. Just another gizmo to make truckers lazier and not have to pay attention, the way of the future for trucking.

    My first choice would be the pressure/temp monitor that mounts to the inside of the wheel. Can’t be stolden and you don’t have to remove them to fill with air like some of the valve stem addons. I had a set that used a “special” too to remove them to airup but on the rear duels it would take a “very long” time to R&R them. So, after a few hundered bucks the whole set up is sitting in my garage. It was hard enough to remove them while sitting in my own yard while the weather was good and no road grime/mud was on the wheels. NOT again. I know some make valve readers that have a flow through to air up-but would still invest in the “inside” the wheel type—BUT they are just a little pricey at the moment.(I do think these are worth every $$ spent on them). I’ll just get out with my pressure guage and do it the way I’ve done for years—but (another but) having some insite as to my tire pressure and temp in the cab is/would be a good thing. Temp reading can also alert you to a brake heating up.

    Add on to my last post–I’m not talking about the readers that replace the valve stem. I like the ones that mount to the inside/lower part of the wheel itself. Held on with super duper double side/stickey tape and a long S/S hose clamp.
