EASY

MISSIONMADE™ products are easy to install and reuse.

LEAKPROOF

Increased band tension secures pipe ends, for a watertight, root-proof

SECURE

Sealing “O” Rings under each clamp prevent pipe end slippage for a reinforced joint seal.

RESILIENT

Synthetic rubbers permit considerable distortion without changing basic physical resistance, unlike thermoplastic gaskets.

ANTICORROSIVE

Stainless steel components resist corrosion in marine applications, poorly aerated/moist soils, contaminated grounds conditions, (e.g.industrial fill sites) and chloride, sulfates or bicarbonates in ground water.

ADAPTABLE

Independent clamp tightening adapts to different outside pipe diameters.

SUSTAINABLE

Certified Cradle to Cradle™ - Manufactured within a 5-Point Continual Improvement process: material health, material reutilization, renewable energy and carbon management, water stewardship, and social fairness.

DURABLE

Synthetic rubber gasket resists ultraviolet rays, ozone, fungus growth, natural soil erosive properties, and normal sewer gases.
