The Quad® P.E. Plus is a patented seal design that combines an injection-molded thermoplastic bearing material with a Quad-Ring® seal, O-Ring, or custom seal to form a self-lubricating seal for both rotary and reciprocating seal applications.
Providing excellent sealing characteristics in a broad range of applications, Minnesota Rubber’s original four-lobed designed seals are available in a full range of standard sizes.
Rubber balls from Minnesota Rubber are carefully molded and precision ground for superior performance in the most critical applications.
