Garlock Style 19 SBR Rubber Sheet

Garlock Style 19 SBR Rubber Sheet

Flange joint leakage in industrial water lines compromises plant operational efficiency. Flange connections require strong structural sealing materials to resist physical deformation under load. We supply genuine Garlock Style 19 SBR Rubber Sheet to maintain your system's operational stability. This premium SBR Rubber Sheet is reinforced with cotton fabric to provide added mechanical strength across piping joints.

Mechanical Advantages and Extrusion Resistance Efficiency

• Cotton Sheeting Reinforcement: Built with a 10.8 oz. cotton insert (5.0 oz. in 1/32" material) to provide exceptional extrusion resistance under bolt loading.
• Homogeneous Rubber Composition: Manufactured using 100% pure SBR rubber without fillers to preserve material integrity and product longevity.
• 80 Durometer Hardness Rating: Features high material density to withstand high mechanical forces on flat face flanges.
• Joint Sealing Integrity: Prevents gasket displacement under operational pressure inside our comprehensive Katalog Gasket collection.
