Walther created the TE series to meet the requirements of couplings with PTFE fittings. This chemically inert and non-corrosive substance is known for its liquid resistance. TE couplings are well suited for hazardous materials, allowing corrosive liquids and harsh chemicals to pass without compromising purity. These couplings also ensure that the couplings are sealed properly so that hazardous chemicals do not leak. The TE family is especially suited for high-temperature applications up to 482 degrees Fahrenheit. For specific TE models, contact one of our sales representatives today.
