3.2 Rev. 12-06 Shaded area indicates changes MUELLER ® NO-BLO ® FORGED STEEL TRANSITION SERVICE TEE FEATURES Mueller NO-BLO Transition Service Tees are designed to give you dependable connections from steel gas mains to plastic service lines. These tees are available in a wide range of sizes and inlet and outlet combinations. Because our transition tees are assembled and permanently joined under controlled conditions, much of the potential for human error is eliminated, with no loose parts or on-site assembly required during installation. Mueller Transition Tee Features o COMPLETION CAPS – are available in Cast Iron and provide a secondary seal. o TRANSITION CONNECTION – exceeds the hydrostatic burst pressure and tensile strength of polyethylene pipe. o MULTIPLE PIGTAIL CHOICES – available in medium or high density polyethylene pigtails in CTS or IPS pipe sizes. Extra pigtail length allows more than one fusion connection attempt if needed. o FUSION EPOXY COATING – resists corrosion. o FORGED STEEL BODY – ensures long-term strength and structural integrity. o CONFORMS TO ASTM D638 and DOT192.283.
