Zero-Flex Style 07, FireLock Style 005 and Transition Style 307 Rigid Couplings have a unique, patented angle pad design which constricts the housing keys into the groove around the full circumference to grip the pipe rigidly. The housings slide on the angled pads rather than mating squarely.

This sliding adjustment also forces the key sections into opposed contact on the inside and the outside groove edges, pushing the joint to its maximum pipe end separation (see chart below) during assembly.

These rigid couplings provide a rigid joint allowing no expansion! contraction or linear movement. Couplings will push the pipe ends to their maximum allowable separation which must he considered during assembly.

Rigid couplings (Styles 07, 005, 008, 307, HP-70, 741 and others) create a rigid joint, useful for risers, mechanical rooms and other areas where flexibility is not desired. Zero-Flex Style 97 and FireLock Style 005 couplings are designed to provide rigidity to permit hanging to ANSI B31.1 Power Piping Code, ANSI B31 .9 Building Services Piping Code and NFPA 13 Sprinkler Systems.

§§ NOTE: These values are based on standard roll grooved pipe. Figures for standard cut grooved pipe may be doubled. See Notes below.

Standard grooved-type couplings allow controlled angular, linear and rotational movement at each joint to accommodate expansion, contraction, settling, vibration, noise and other piping system movement. These features provide advantages in designing piping systems but must he considered when determining hanger and support spacing and location.

Victaulic couplings offer superior vibration attenuation characteristics to both flexible metal and elastomeric flexible arch-type connectors.

Independent vibration testing data (request 26.04) verifies that three Victaulic couplings in close proximity to a vibration source (pump, equipment, etc.) provide superior vibration attenuation in piping systems.

Both type couplings otter installed cost savings from 10 to 30% and higher, plus the convenience of a union at every joint and the proven. pressure-responsive "C" shaped Victaulic gasket. Both type products fit into standard roll or cut grooved pipe and provide the security of all circumferential engagement of the coupling housing into the groove for high pressure and end load service.

General Notes for Dimensional Tables

* Working Pressure and End Load are total, from all internal and external loads, based on standard weight (ANSI) steel pipe, standard roll or cut grooved in accordance with Victaulic specifications. Contact Victaulic for performance on other pipe.
WARNING: FOR ONE TIME FIELD TEST ONLY, the Maximum Joint Working Pressure may be increased to 1 to 1 1/2 times the figures shown.
§§ Allowable Pipe End Separation and Deflection figures show the maximum nominal range of movement available at each joint for standard roll grooved pipe.
Figures for standard cut grooved pipe may be doubled. These figures are maximums; for design and installation purposes these figures should be reduced by: 50% for 3/4 - 3 1/2" (20 - 90 mm); 25% for 4" ( 100 mm) and larger.
Number of bolts required equals number of housing segments.
Metric thread size bolts are available (color coded gold) for all coupling sizes upon request Contact Victaulic for details.
WARNING: Piping systems must always be Repressurized and drained before attempting disassembly and removal of any Victaulic piping products.

All products shall be installed in accordance with current Victaulic installation/assembly instructions.
Victaulic reserves the right to change product specifications, designs and standard equipment without notice and without incurring obligations.
