Fabricated Spools

Changing out old water meters for new ones can mean changes in water meter sizes. Advancements in water meter design has led to meters leaving Utility Water Departments and Water Meter Shops with gaps in lay lengths to address upon installation. MARS fabricated spools with or without test ports are used as spacers to make up this difference when exact lay lengths are needed.

MARS Test Port Spools assist in testing the water meter for accuracy without the need to remove the meter from the field, expediting time and giving you your test results faster. Our standard size coupling is 2” Carbon Steel with custom sizes available, just specify your requirement.

As a sole source, MARS Company Spools comply with all AWWA C207 design requirements and AWWA C213 material requirements. NSF61 Certified.
