Mission Rubber MR56 100 (N)

Flexible, unshielded sewer couplings connect 1 Inch cast iron or plastic pipe to 1 Inch cast iron or plastic pipe. For non-pressure, gravity flow applications only. Recommended for underground installations, although some jurisdictions will allow use above ground. Easy to install and reuse. Custom, large diameter sizes available.

Mission Rubber Sewer Coupling, Series: MR56 Series, Flex-Seal®, 1.4 x 1.4 Inch Nominal, Synthetic Rubber, Material Specification: ASTM C425/C1173, 2 Inch W

• MR56 Series couplings are used to join cast iron or plastic to cast iron or plastic
• Mission’s Flex-Seal® Unshielded Coupling is a flexible sewer coupling designed to connect similar and dissimilar pipe materials and sizes
• Coupling consists of two (2) 300 series stainless steel worm drive clamps over a molded one-piece elastomeric sealing gasket
• Leakproof seal - Stainless steel clamps provide a positive seal when properly tightened to 60 in/lb of torque
• Axially slotted clamps enable bands to tighten independently to accommodate variances in the outside diameters of the pipe to be joined, ensuring a watertight, leakproof and rootproof seal
• Sealing "O" rings are installed under each sealing clamp to prevent pipe slippage and create a more positive seal
• Corrosion resistant - use of 300 Series stainless steel components are highly effective in a variety of environments; such as marine applications, poorly aerated or moist soils, contaminated ground conditions (particularly industrial fill sites) and where the ground water contains chloride, sulfates or bicarbonates
• Withstands tension and compression - synthetic rubbers permit a substantial degree of distortion without change in basic physical resistance, unlike other manufacturers’ thermoplastic coupling materials
• Molded synthetic rubber gasket is strong, durable and resilient to ultraviolet rays, ozone, fungus growth, natural erosive properties and normal sewer gases
• More pliable and easier to install in cold weather applications than an elastomeric PVC gasket
• Pre-set calibration - all Flex-Seal® unshielded couplings are designed to be installed with a pre-set torque wrench calibrated to 60 in/lb maximum to accommodate the 300 Series stainless steel 5⁄16 Inch hex head screw
• 1000 psi minimum tensile strength
• 250% minimum elongation
• 55 - 70 Durometer (Shore A)
