Swagelok MS-MHSU-IG-1410 Gap Gauge

Swagelok MS-MHSU-IG-1410 Gap Gauge is a precision gap inspection tool for Swagelok 7/8 in fittings, used to verify makeup after tightening with a Swagelok multihead hydraulic swaging unit (MHSU) or other approved methods. The gauge accommodates two metric nut sizes, 20 mm and 22 mm, which correspond to the Swagelok 7/8 in fitting family. Identified by part MS-IG-1410, this gauge is positioned beside the joint after installation to confirm the nut has been drawn up to the correct depth, helping ensure a secure, leak-tight connection and consistent makeup across assemblies. It is part of Swagelok’s gap inspection gauge lineup, designed to provide a quick, objective check of makeup during maintenance, field repairs, or new installations in instrument, process, and laboratory piping systems. When used with Swagelok MHSU tooling, the MS-MHSU-IG-1410 provides a tangible, repeatable reference for proper joint engagement, reducing the risk of under- or over-tightening. The gauge’s 7/8 in size and dual 20 mm/22 mm compatibility cover common Swagelok fittings, making it a standard accessory for technicians working with 7/8 in tube fittings.
