Asc 390200061 Fig 7003 Hingelok Coupling 3 in Grooved

Product Description

The ASC ENGINEERED SOLUTIONS 390200061 is the FIG 7003 HingeLok grooved pipe coupling designed for fast connection and disconnection of pipe joints without additional tools. Built from ductile iron with a rust-inhibiting orange paint finish and fitted with an EPDM gasket, this coupling handles system working pressures up to 300 psi. The cam-action locking handle snaps the two permanently hinged coupling halves into the pipe grooves and secures them quickly, while a locking pin provides an additional layer of security at critical joints. Licensed plumbers and pipefitters install this coupling in mechanical piping systems where maintenance access or frequent pipe removal is a regular requirement.

The FIG 7003 HingeLok coupling is sized for 3 inch nominal pipe with a 3.5 inch outside diameter and uses a grooved end connection style. It is suited for residential and commercial mechanical piping installations where the system demands rapid assembly cycles, periodic disconnection for maintenance, or reliable re-engagement under pressure. The EPDM gasket makes it appropriate for water-based systems and general-purpose fluid service. Toggle link plates at this size range secure the cam-action handle to the housing for a reliable, repeatable lock.

Key Features

• Permanently hinged coupling halves simplify handling and speed up installation
• Cam-action locking handle closes and secures without additional tools
• Locking pin adds extra security at critical pipe joint locations
• Rated for system working pressures up to 300 psi (20.7 bar)
• EPDM gasket included for water-based and general fluid service applications
• Ductile iron body with rust-inhibiting orange paint for corrosion resistance

Compatibility

Designed for use with 3 inch nominal grooved pipe having a 3.5 inch outside diameter. Compatible with standard grooved piping systems within the FIG 7003 series product family.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable mechanical and plumbing codes. Depressurize and drain the system completely before removing or installing any coupling. Confirm the pipe groove dimensions conform to the coupling specification before assembly, and verify the locking pin is fully seated before returning the system to service.
