lead yarn gas joint sealant

Flexspray Sealant

Flexspray Sealant is a two-part anaerobic system formulated to seal leaking mechanical and run lead joints on cast & spun iron, steel & ductile gas mains.

Unlike other anaerobic solutions, Flexspray contains a Flexibilising additive that enables the joint to move and stay sealed.

It is formulated to fully seal all the joints using capillary motion, ensuring a complete seal.
