The Marathon Straight Rubber Couplings have been engineered to provide a leakproof seal connection on many pipe materials. Marathon couplings provide a high-quality and user-friendly installation. Applications include, but are not limited to sewer and in-house connections: seals against infiltration and exfiltration, drain, waste, vent piping, house to main, retrofit, repairs, roof drains, and cut-ins. The compounds utilized to manufacture will provide long-term installed life and are not affected by soil. Furthermore, the coupling is resistant to chemicals, ultraviolet rays, normal sewer gas, fungus growth, and root resistance. All couplings are designed to be installed with a pre-set torque wrench calibrated at 60-inch pounds to accommodate the 305 stainless steel 5/16” hex head fasteners.
