High Performance Seals

As part of our money saving strategies for the winter we have been checking for leaky sinks.  We discovered we did have one sink that was leaking, a very slow constant drip.  After turning the water off and taking the sink head apart we discovered it only needed a new rubber O-ring.  Parco specializes in high-performance seals and is the industry lead in the development of proprietary rubber compounds and bonding techniques. Parco was actually the first manufacturer to specialize in O-rings and is still their primary product.  Parco is a very hands on company selling to many Fortune 500 companies.  They make their own molds, mix their own rubber and mold their parts in computer-controlled presses. They cater to six major industries; oil field machinery, military & aerospace, water filtration, motor vehicles, farm & construction and fuel-dispensing.
