Overview

The Dresser STAB-40 is the long-sleeve version of the STAB packaged pipe joint: a Style 40 long coupling that leaves the factory fully assembled. Its 12, 16 or 24 in middle ring bridges a gap or a cut-out section of steel pipe, and the crew slides it on and stabs the pipe in without taking anything apart.

Application: Closing gaps and replacing short damaged sections on steel gas pipe.

  • Ships assembled for stab installation
  • 12, 16 or 24 in middle ring
  • Every variant ends with the Dresser part number
Lead Time: 4 to 6 Weeks

STAB couplings are built to order by Dresser. Allow 4 to 6 weeks from order to shipment. Call 1-888.510.4036 to confirm the current lead time before you schedule the job.

What STAB Means

STAB is Dresser's name for its pre-assembled couplings: the crew stabs the pipe end into a coupling that is already put together. The coupling itself, middle ring, followers, gaskets and bolts, is the same design as the standard Style 40. The difference is how it arrives and how fast it goes in.

STAB Standard Style 40
How it ships Factory assembled, no loose parts, one marked carton Ordered as a coupling, and parts such as gaskets are also sold separately
Installation Slide on, stab the pipe in, center, tighten. No disassembly Assembled onto the pipe from its parts
Gaskets Armored or armored pinned Grade 27 Buna-S Choice of gasket grades
Sizes 2 in to 12 in steel pipe Wider size range and pipe types
Best for Gas crews who want fast, repeatable joints and simple stocking Special gaskets, sizes or pipe types
Installation in Brief
  • Clean both pipe ends to bare metal so the gaskets seat on steel
  • Chalk a centering mark 14 in from each pipe end
  • Lubricate gaskets and pipe ends with soapy water; add anti-freeze in freezing weather
  • Slide the coupling onto one end, stab the other pipe in until the ends meet, then back it out 1/2 in to 1 in for deflection and expansion
  • Center the coupling between the chalk marks and tighten the nuts a turn or two at a time around the pipe, to at least 80 ft-lb
  • Maximum deflection after tightening: 6 degrees on 2 in, 4 degrees on 3 in to 12 in

Before You Order. The coupling seals but does not restrain the pipe: anchor it wherever pullout could occur. Measure the gap and the pipe OD before ordering. For other sizes, builds or a factory submittal, email sales@watermainsupply.com with the pipe OD, material and line content.
