The flexible grooved coupling connects grooved piping in fire protection networks when the layout needs to allow small alignment variations, vibration or controlled movement without welding or threading. It is manufactured in ASTM A536 ductile iron and specified for systems with UL/FM listed components, provided the final selection is compatible with the project's pipe, groove and gasket. Its main difference compared with a rigid grooved coupling is the ability to allow limited deflection and displacement between ends, making it useful in areas with direction changes, equipment, pumps or runs where installation requires tolerance. Selection should not be based only on price: diameter, groove type, elastomer, wet or dry system application and fire protection network approval requirements must be reviewed.

It varies by diameter, gasket, requested approval and purchase volume. TECTUL quotes per unit and can consolidate fittings for site work.
The flexible type allows limited movement and helps in runs with vibration or installation tolerances. The rigid type maintains a firmer, more aligned joint.
The groove is checked, the compatible lubricated gasket is installed, the housings are positioned and the bolts are tightened alternately.
It may be useful because of its movement tolerance, but it must be checked against the design, supports, expected vibration and system approval.
Diameter, quantity, gasket type if defined, delivery city, system use and whether UL/FM documentation is required.
Yes, when the groove and diameter are compatible with the coupling and with the fire protection network system requirements.

The dimensions, thicknesses, pressures, temperatures and other characteristics stated in this data sheet are theoretical nominal reference values, compiled from publicly available technical sources: international standards (ASME, ASTM, API, MSS, ISO and NTC, depending on the product) and published engineering literature. They are average approximations intended to guide selection, not a certificate of conformity for any given lot.
Actual values may vary due to conditions inherent to the manufacturing process — dimensional and wall-thickness tolerances (in pipe, typically ±12.5%), surface finish and residual stresses from forming or welding — and to factors inherent to the raw material — chemical composition variations within the ranges allowed by the standard, inclusions or heat-to-heat differences. They may also be affected by in-service events not foreseeable at design time: water hammer, vibration, thermal and mechanical fatigue, corrosion and operating overpressures, which can cause the element to fail before its estimated service life.
To know the certified behavior of a specific lot, TECTUL supplies upon request the manufacturer's mill test certificate (MTC) issued per the product standard; for critical applications, laboratory testing of the lot can also be arranged. In the absence of such certification, the data provided here must not be used as the sole criterion in critical or safety applications, or wherever the integrity of the line may compromise the lives of people or property; in such cases, consult our technical team first.
