We manufacture a huge variety of rubber plugs with varying dimensions and specifications according to our customers’ specific needs. Some of their main applications are sealing copper tubing, sealing steel tubing, sand blast protectors, and paint line protectors, among others.

Rubber profiles can be manufactured whether by compression molding, or transfer or injection process.

These items are produced with raw materials like natural rubber (NR) and different synthetic rubber such as ethylene propylene diene terpolymer (EPDM), nitrile (NBR), neoprene (CR), styrene butadiene (SBR), among others with a hardness range of 30 to 90° Shore A.

Hultek is prepared with the infrastructure to offer our customers specialized technical assistance if needed, starting with the compound development, mold manufacturing, prototype tests, definitive molds, and up to mass production.
