The sleeve shall have as a minimum 7/8" wide gasket of Nitrile Butadiene Rubber (NBR, Buna-N) per
ASTM D2000 with hydromechancial activated lip, captured in a recessed groove around the outlet; 3/4"
corrosion resistant, high strength low alloy oval neck track head bolt per ASTM A242/ANSI 21.11/AWWA
C-111 and heavy hex nut per A563 epoxy coated and a 3/4" forged steel test outlet. Flanged outlet shall
be AWWA C207 Class D, ANSI 150 lb. drilling, recessed for tapping valve per MSS-SP60, outlets 2” – 12”
rated for 175 PSI* maximum operating pressure. Tapping Sleeve shall be furnished with corrosion

For outlet sizes 14" and larger, the gasket groove must be consistently positioned about throat of tapping
waterway. Inside diameter of the gasket groove must be set back a minimum of 1" from the waterway to
allow dispersal of forces generated by gasket compression. Gasket grooves machined in a circle and
formed to an elliptical shape will not be an accepted equal.

Nominal pipe sizes 36" and larger shall be of the heavy duty type. Tapping Sleeves shall be JCM 412 or
approved equal.
