SWANLAKE Valve Lapper Set With 4 Suction Plates

As sold for lapping valves, it works as advertised! The spare suction cups are an added bonus! Keep the spares in a refrigerator so they last longer until you need them.

These work very well. Both ends hold well. Gotta wet them a bit. Set centered on valve and push. Found them to hold very well.

I ended up using a shot out of a spray can of adhesive to get the suction cups to stick much better and that really helped and saved a ton of time lapping the valves. It took for ever on the 1st head because they keep not sticking and all of my time went to doing it slow so the suction cups would not come off. A little shot of adhesive spray will keep them on and help u roll through all the valves. W the spray adhesive they worked great

there as good as I expected. the price was great, and I like them will make my work last longer. Thank you.

ported my minibike head and relapped the valves, wet the suction cup before use.

Easy to use

They do not suction very good, but worked good enough to get a decent lap with compound.

I hadn’t lapped valves since high school and these worked great on a lawnmower engine
