Dresser engineers combined the versatile features of our Style 50 bolted mechanical sleeves with Intervention Solutions LS2 weld fittings to provide factory-integrated sleeves for hot tapping or line stopping cast-iron mains under pressure. As a complete factory-built product, Dresser hot tap sleeves help reduce inventory while eliminating the problems associated with field welding installations. What's more, LS2 weld fittings are also offered with side outlets in a variety of sizes to accommodate steel and P. E. branch service connections when joined with Dresser Style 711 bolted or Style 700 hydraulic couplings.
