The Weiss Instruments WEISS-LF441-015-4L is a stainless steel liquid filled industrial pressure gauge built for demanding service environments. It is designed to perform reliably where vibration, corrosion, and pulsating pressure conditions are present. The liquid filled construction dampens pointer movement caused by mechanical shock and pressure spikes, extending service life and maintaining readability. This gauge is suited for installation on process piping, pumping systems, compressors, and fluid handling equipment. Licensed trades including plumbers, pipefitters, HVAC technicians, and industrial mechanics are the typical installers.
This gauge is part of the Weiss Instruments stainless steel industrial series, which covers a wide range of accuracies, case patterns, and construction materials. The stainless steel case and wetted components make it appropriate for corrosive media and harsh ambient conditions found in industrial, commercial, and heavy mechanical service applications. It is well suited for both indoor and outdoor installations where standard gauges would be prone to premature failure.
Designed as an OEM-style replacement or direct-install industrial pressure gauge for process piping, pumping, and fluid handling systems requiring stainless steel wetted construction and liquid filled vibration resistance.
Installation should be performed by a qualified plumber, pipefitter, or mechanical technician familiar with pressure instrumentation. Isolate and depressurize the system completely before removing or installing any gauge. Apply appropriate thread sealant to the gauge connection per the fitting manufacturer and applicable code requirements. Do not overtighten the gauge connection, as this can crack the socket or distort the bourdon tube.
