Mechanical Pipe Joining

Grooved fittings, couplings & accessories.

A coordinated joining system for HVAC, fire protection, plumbing and water applications—specified as compatible components rather than isolated fittings.

System Components

Designed to work as a complete joint.

The pipe groove, coupling housing, gasket, bolts and fitting dimensions must suit the same system and service conditions. Gasket compound, pressure rating, approval and coating are verified at quotation.

Rigid couplings
Flexible couplings
Elbows and tees
Reducers and caps
Mechanical outlets
Flange adapters
Grooved valves
EPDM or nitrile gaskets

Products, sizes & selection details.

Ranges vary significantly by manufacturer and series. The extended fitting range may reach 24 inches; project demand is quoted item by item.

Do not mix by appearance: groove profile, gasket, pressure rating and approval must be compatible with the selected manufacturer’s system.

Grooved product range

Product	Indicative nominal range	Selection information
Rigid couplings	1–12 in; extended series by enquiry	Pipe OD, groove type, pressure and coating
Flexible couplings	1–12 in; extended series by enquiry	Movement requirement, gasket and pressure
Elbows & tees	¾–24 in, product dependent	Angle, equal/reducing branch and material
Reducers & caps	1–12 in; larger by series	Concentric/eccentric where offered
Mechanical outlets	Branch and run size by model	Threaded or grooved outlet, pressure and approval
Flange adapters	2–12 in; larger by system	Mating flange standard and pressure class
Grooved valves	2–12 in typical product coverage	Valve type, duty, pressure and required approval

Materials and requirements

Component	Common specification basis	Confirm with RFQ
