12-Month Smith-Blair Warranty
Smith-Blair warrants its products to be free of defects in materials and workmanship for one year from the date of shipment by Smith-Blair. Dated proof of purchase, such as a bill of sale, is required to establish eligibility. Smith-Blair will repair or, at its option, replace a defective product; the product is returned to the factory or warehouse Smith-Blair designates.
Working Pressure
Up to 150 PSI. Smith-Blair rates the allowable working pressure of a repair clamp to fall as pipe diameter rises; for a particular installation it is set by pipe size and type, the type and extent of the damage, service conditions and installation workmanship.

Installation Notes
- Clean the pipe where the clamp will sit, removing scale, dirt and debris that could spoil the gasket seal, and lubricate pipe and gasket with a soap-and-water solution.
- Snap the gasket cartridge around the pipe, centered over the leak, with the gasket split 180° from the damaged section.
- Rotate the band so the bridge-plate dimples sit centered between the open and closed lugs, engage the bolt head in the open lug, and tighten to the torque in the instructions.
- Joining pipe on gas lines: use a different clamp; the 244 and 247 are not for that service.
- Repairing or connecting separated pipes: the 244 can act as an insulator, so install a jumper wire where electrical continuity is required (grounded or cathodically protected systems).
- Anchor the pipe: the clamp seals around it, and Smith-Blair requires proper anchoring to restrain pipe movement and prevent pull-out.
