Be the first to review
Color:One Color



The first step in locking threaded assemblies.

Apply the Park Tool Adhesive Primer as the first step in prepping surfaces and accelerating the curing process for component installation and fastener use, such as applying a retaining compound or threadlocker to carbon frames. Please note, you'll need to use this with Park Tool's TLR-1 and TLR-2 Threadlockers or the RC-1 Retaining Compound to prevent permanently bonded parts. It's common as a first step application in installing PF30 bottom brackets and pressing bearings into carbon fiber frames.
