Custom
Drilling & Fabrication
 We
have many size hole drills available to drill any size stopper.
We offer custom machine fabricated stoppers and small machine fabricated
rubber parts. When small to medium quantities are needed these fabrication
options eliminate the cost of custom molding. We fabricated from most
any elastomeric rubber with no limitation on size.
Our
other custom molded and fabricated rubber parts capabilities include:
Plugs, Sleeves, Washers, Bumpers, Ferrules, Seals, Spacers and Lathe
cut gaskets.
