EASY

MISSIONMADE™ products are easy to install and reuse.

LEAKPROOF

Increased band tension secures pipe ends, forming a watertight, root-proof seal.

SECURE

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

ANTICORROSIVE

Stainless steel components resist corrosion in various environments.

ADAPTABLE

Independent clamp tightening adapts to different outside pipe diameters.

RESILIENT

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

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.
