Ashcroft 83220XLL Pressure Gauge 0-15 Psi 3.5 in Lower Mount

Product Description

The ASHCROFT 83220XLL is an analog industrial pressure gauge built for accurate, reliable pressure monitoring in demanding service environments. It features a 3.5-inch dial graduated from 0 to 15 psi and is fitted with a 1/4-inch MNPT lower-mount connection. The case and wetted parts are stainless steel, with a 304/316 stainless steel case and a 316 stainless steel Bourdon tube. Accuracy is rated at 1 percent of scale. The polycarbonate lens protects the dial face from moisture and debris without requiring a liquid fill. This gauge is a dry-type instrument suited for technicians and plumbers monitoring low-pressure gas, water, or fluid systems.

The 83220XLL suits residential and light commercial applications where a compact, corrosion-resistant pressure gauge is required. Typical uses include monitoring supply pressure on plumbing systems, low-pressure pneumatic circuits, compressed air lines, and water treatment equipment. The lower-mount MNPT connection allows direct installation into standard pipe fittings or manifold ports. The stainless steel wetted parts make it appropriate for mildly corrosive media as well as clean water and air service.

Key Features

• 316 stainless steel Bourdon tube and stainless steel wetted parts for corrosion resistance
• 304/316 stainless steel case provides durable protection in industrial settings
• 1 percent of scale accuracy for reliable pressure measurement
• Dry gauge construction with no liquid fill — simplified service and disposal
• Polycarbonate lens rated IP54 and IP65/NEMA 4 for dust and moisture protection
• Meets CRN, PED, and RoHS standards

Compatibility

Designed as an OEM-style replacement or direct-install industrial pressure gauge for systems using a 1/4-inch MNPT lower-mount port across plumbing, HVAC, pneumatic, and light industrial applications.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off system pressure and bleed down to zero before removing any existing gauge or installing this unit. Apply thread sealant tape or compound to the MNPT threads per local plumbing code — avoid over-tightening, which can crack the socket. Confirm the operating pressure of the system does not exceed the 15 psi maximum range of this gauge before placing it in service.
