No—preformed Torca band clamps apply even clamping force and are designed to avoid deforming properly sized butt-joint connections.

Neither is typically required when the pipes are properly aligned and sized. Clean mating surfaces and tighten evenly for a gas-tight seal.

Yes. One benefit of Torca band clamps is serviceability—components can be removed and reinstalled as needed.
