Tolco Pro-Blend Proportioner Caps

Take the guesswork out of mixing chemicals with the Tolco Pro-Blend Proportioner Caps. Designed to give you a quick, clean and accurate dilution every time, these caps eliminate spillage and prevent wasted product. Whether you’re preparing shampoo, APC, wheel cleaners or any concentrated detailer, you can dilute like a pro with zero fuss.

You’ll enjoy a smarter workflow thanks to a built-in measuring reservoir that allows you to draw up the correct amount of product without removing the cap. No more measuring cups, no more messy pours — just precise dilution ratios with a simple squeeze. It’s ideal for mobile detailers, busy workshops or anyone wanting consistent results every time.

Available in two neck sizes sizes, you can select the right fit for your favourite detailing chemicals. The 28mm neck size suits many smaller bottles including popular brands such as Alchemy, Auto Finesse, Carbon Collective, CarPro, Chemical Guys, Clean, DIY Detail, Dodo Juice, Finish Kare, Garage Therapy, Gtechniq, Gyeon, Infinity Wax, Optimum Polymer, P&S, Poorboys, Stjarnagloss, Zaino, Zymol and more. The 38mm neck size fits larger bottles such as Gallon / 5L containers and is compatible with brands such as Auto Finesse, Chemical Guys, Meguiar’s, Optimum Polymer, and Valet Pro (1L & 5L), among others.

Because manufacturers can change bottle specifications at any time, we always recommend checking your bottle neck size before ordering. If you're unsure, just contact us — we’re happy to help ensure you get the perfect match.
