MODEL G-28 HINGED LEVER COUPLING

The Model G-28 Hinged Grooved Coupling is designed for quick connect and disconnect services. The housing segments are hinged with a lever handle for easy assembly. The use of the split pin can secure and prevent the accidental opening of the coupling. The Model G-28 can be used in a wide variety of applications with standard rolled or cut grooved pipe. Housings 1½”- 4” (40 mm – 100 mm) feature a smooth outer surface, housings 5” - 12” (125 mm – 300 mm) feature a cross-ribbed design for added strength.

Standard gasket: Grade “E” EPDM or Grade “T” Nitrile.

Standard surface finish: Black electro-deposition coated.

*Working pressure is based on roll grooved standard wall carbon steel pipe.

^The ASME/ANSI pressure class rating is not the design or maximum pressure rating, rather is provided for those that are accustomed to specifying or using ASME/ANSI pressure class rated components such as flange, valves, etc.

† Allowable Axial Displacement and Angular Movement (deflection) figures are for roll grooved standard steel pipe. Values for cut grooved

pipe will be double that of roll grooved. These values are maximums; for design and installation purposes these figures should be reduced by: 50% for ¾” – 3½”; 25% for 4” and larger to compensate for jobsite conditions.

** Deflection or angular movement is the maximum value that a coupling allows under no internal pressure.

Performance Data

The following tables show the maximum working pressures (CWP) of Shurjoint Model G-28 Hinged Lever Coupling used on both carbon steel and stainless steel pipes. Shurjoint ductile iron couplings can be used in conjunction with stainless steel pipe in non-corrosive environment as the flow media does not come in direct contact with the coupling housings but rather only the gasket.

Expansion Pipe

Lever handles are factory assembled pretty tight for safety sake. The use of an expansion pipe will be of help for an easy opening or closing. Expansion pipes are available upon request.

Expansion Pipe		Applicable Coupling
size		Sizes
½” x 6”	1½" ~4"

¾” x 8”	5" ~ 8"

(You can easily make your expansion pipe simply by cutting sch. 40 ½" or ¾" pipe to a proper length)

Warning:

Lever handle couplings are not recommended for services where excessive shock-loads are present, as often occur in some concrete pumping applications. When the Model G-28 is used in concrete pumping applications, sound support and bracing practices should always be in effect. All couplings and components should be regularly inspected to ensure they are in good working condition and that the pipe grooves, coupling keys, and gasket are free of any concrete or foreign material.

For concrete pumping applications we recommend the Shurjoint Model S58 shoulder coupling and Shurjoint Model S10 abrasion resistant 90o elbow.

General Notes:

ASME/ANSI Pressure-Temperature Rating is provided as an aid in selecting a proper coupling to incorporate with other piping components (valves, flanges, and etc.) that are used in the same system and carry the ASME/ANSI rating. Select a Class 150 coupling to incorporate with Class 150 valves and flanges.

Maximum Working Pressure (CWP) listed is the maximum cold water pressure for general piping services tested to ASTM F1476 and or AWWA C606 methods. Figures listed are based on roll- or cut-grooved standard wall carbon steel pipe. For other pipe schedules or pipe materials, contact Shurjoint for additional information.

Max. End Load is calculated based on the maximum working pressure (CWP).

Field Joint Test: For one time only the system may be tested hydrostatically at 1½ times the maximum working pressure listed (AWWA C606 5.2.3).

Warning: Piping systems must always be depressurized and drained before attempting disassembly and or removal of any components.

The 10 Year Limited Warranty applies to manufacturing defects only and does not cover severe service/temperature applications or wear parts.

Shurjoint reserves the right to change specifications, designs and or standard without notice and without incurring any obligations.
