The FlowMaster Dual Chamber Orifice Fitting is a proven system for safely and quickly inspecting and changing orifice plates without breaking or depressurizing the flow line.

With the FlowMaster Orifice Fitting sealing system, there is no need for lubrication or greasing.

Designed and builded in compliance with ISO 5167, AGA-3, ASME B16.5, ASME B16.34 and MSS SP-55 Standards.

• All FlowMaster Orifice Fittings come standard with a documentation package including hydro-test, inner valve seal test, liquid dye penetration test, and quality control inspection reports.
• The fittings are manufactured within the guidelines of ASME 16.34 and ASME 16.5.
• Traceability is maintained in accordance with the ISO 9001 Quality Control System.
• When required, radiography, stress relief, ultra-sonic, magnetic particle, function, and material tests can be performed with the relevant reports submitted.
