Milkit Compact 45 Tubeless Check & Refill Kit

No Mess & No Air Loss Even Without The Valve Core
milKit patented tubeless valve system is quick and easy to use.

The solution to combat sealant drying out or escaping! With other tubeless tire valve systems you need to remove the tire to check if enough sealant remains, with milKit you can simply remove the valve core and insert the syringe to check. No mess and faster results!

The syringe holds 60ml or 2 oz of fluid and comes with a flexible connector and a large needle to push through the valve and rubber flaps. There’s also a sealant regulator that screws into the syringe for easy refilling. The needle has an angled end for effective removal of all sealant in the tire.

Patented milKit presta bike valves are made in Germany from anodized high quality aluminum alloy and high performance rubber for the smart flaps.

The standard milKit valves have a usable length of 35 mm and they work for most road and mountain bike rims except some special high-profile rims. For high-profile rims, there are 45mm, 55mm and 75mm versions of the milKit valves available.

milKit valves can be used with most sealants, but we recommend milKit sealant. This has been specially designed for best results with these valves.

Replacement valves & valve cores are also available.
