Installation Notes
  • Clean the pipe and confirm it falls in the sleeve range with a pi tape.
  • Lubricate the pipe, gasket and spanner surfaces with soapy water; no grease or pipe lubricant.
  • Tighten the nuts in a criss-cross pattern to the label torque, keeping the spanner gap uniform on both sides.
  • Block and shim the tapping valve so the valve and machine weight never loads the outlet; the outlet must not rotate on the pipe.
  • Hydrostatically test through the 3/4 in test port before tapping; never test with compressed gas.
  • Water service only, not gas; on PE/HDPE the maximum install and operating temperature is 85°F.

Before You Order. Measure the pipe OD with a pi tape and confirm the outlet and flange type. Anchor the pipe: this product seals but does not restrain, and Dresser requires the pipe joint to be anchored wherever pull-out can occur. Non-stock Dresser parts are not returnable without Dresser’s authorization, and ship time is confirmed when you order. Custom builds (other sizes, widths, gaskets or materials) are available: email sales@watermainsupply.com with the pipe OD, material and line content.
For engineering-led sizing and selection support or a factory submittal, email sales@watermainsupply.com or call 1-888.510.4036.
