Description
A Edwards Dowty seal is made to exact specifications. The rubber compound is chosen to resist hot pump oil. The metal ring is the right size to fit your pump perfectly. Choosing parts protects your pump from leaks and ensures a reliable seal.
A Dowty seal is not a regular O-ring. It is a special type of seal. It looks like a metal washer with a rubber ring bonded to the inside . When you tighten it down, the rubber compresses and creates a tight seal. The metal outer ring protects the rubber from being squeezed out.
Think of it like a high-quality washer. It is designed to seal threaded connections that see oil pressure. It works much better than a plain metal washer or a regular O-ring alone.
