The rigid grooved coupling joins two grooved pipe ends forming a joint that restricts deflection and keeps the run aligned. Housings are ASTM A536 grade 65-45-12 ductile iron, the gasket is EPDM and the groove follows ANSI/AWWA C606-22. Fire protection networks require components listed to UL 213 and FM 1920 approved.
| Feature | Specification |
|---|---|
| Housings | Ductile iron ASTM A536, grade 65-45-12 (minimum tensile strength 448 MPa / 65 ksi) |
| Groove profile | Per ANSI/AWWA C606-22 — grooved and shouldered joints |
| Gasket | EPDM for water; other elastomers confirm when quoting |
| Fire network listings | UL 213 (rubber gasketed fittings for fire-protection service) and FM 1920, required by NFPA 13, 2025 edition |
| Working pressure | Up to 300 psi (20.7 bar) in typical commercial sizes of the type; varies by diameter and model — confirm per listing when quoting |
| Function | Rigid joint: restricts angular deflection and rotation between runs |

The rigid one limits movement between pipes and keeps the run aligned; the flexible one allows controlled angular deflection and absorbs small system movements. Both mount on an ANSI/AWWA C606-22 groove.
Housings are ductile iron ASTM A536 grade 65-45-12, the groove follows ANSI/AWWA C606-22 and fire networks require components listed to UL 213 and FM 1920 approved, per NFPA 13, 2025 edition.
Commercial models of the type typically reach up to 300 psi (20.7 bar) working pressure; the exact value depends on diameter and listed model and is confirmed with the manufacturer data sheet when quoting.
Grooves are cleaned, the compatible lubricated gasket is installed, the housings are placed and the bolts are tightened alternately to uniform closure, without forcing the pipe.

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.
