Overview
The Weiss 4CTSLF is a 4½" lead-free pressure gauge purpose-built for potable water applications, certified UL in accordance with NSF/ANSI 372. Its drawn stainless steel case with a push-in Lexan window and phosphor bronze tube deliver reliable, corrosion-resistant performance in plumbing, HVAC and food-service systems.
Working Principle
Process pressure acts on a phosphor bronze Bourdon tube, driving a slotted adjustable pointer across a white lithographed dial — every wetted material in the pressure path (solder, socket) is lead-free brass to meet potable water certification requirements.
Applications
Benefits
- Meets potable water lead-free compliance requirements out of the box
- Standard 1/4" NPT bottom connection fits common HVAC/plumbing installs
- Matching lead-free valves and thermowells simplify full system compliance
