Flexible, unshielded sewer couplings connect clay pipe to cast iron or Schedule 40 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.

• Mission's Flex-Seal unshielded coupling is a exible sewer coupling designed to connect similar and dissimilar pipe materials and sizes
• Coupling consists of (2) 300 series stainless steel worm drive clamps over a molded 1-piece elastomeric sealing gasket
• Leak-proof 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, leak-proof and root-proof 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 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 in hex head screw
