• Tyler pipe standard coupling sealing sleeves conform to ASTM standard C564 and are made of high purity neoprene This material delivers superior-resistance to decay and deterioration from contact with effluents in the pipe, chemicals in the soil or air around the pipe including oil and other petroleum products Each sleeve features a double row of raised, sealing rings positioned under each compression band to provide multiple, sealing surfaces on either side of the connection This ensures a permanent, leak-proof joint that can reliably accommodate minor, pipe-mating diameter variations Tyler couplings incorporate a shield and clamp assembly fabricated from 300 Series stainless steel for maximum corrosion-resistance Clamping bands are mounted and attached to the shield by a fixed and floating eyelet system that allows for variable adjustment of each clamp during tightening Our shield's patented diamond pattern corrugation design locks the sealing sleeve under the shield and prevents slippage or extrusion - even under elevated internal pressure or external stress Horizontal pipe and fittings 5 in and larger should be suitably braced using blocks, rodding or other methods at each branch or change in direction A superior gasket joint is produced with a Tyler pipe standard no-hub coupling It is designed not to leak, even when subjected to vibration, seismic tremors, expansion, contraction, deflection by as much as 5 deg or external and internal test pressure Tyler pipe internal quality control processes include daily performance testing to verify conformance of all components to established standards

Tyler pipe and coupling standard no-hub couplings are manufactured in accordance with CISPI 310 and are designed to join cast iron pipe and fittings in drain, waste and vent applications. Each coupling includes two components a molded, one-piece neoprene sealing sleeve and a 300 Series AISI stainless steel shield/clamp assembly featuring compression bands over our trademark diamond corrugation shield pattern.
