2" x 1/4" Brass Pressure Gauge, Lead-Free, 30 PSI

Campbell PG3T-NL – 2" Lead-Free Brass Pressure Gauge, 1/4" NPT Lower Mount, 0–30 PSI

The Campbell PG3T-NL is a compact analog pressure gauge designed for low-pressure system monitoring. With a 2-inch dial and 1/4" NPT lower mount, this model is rated for up to 30 psi and is well-suited for closed-loop systems, water filtration units, and other low-pressure fluid applications.

Manufactured with lead-free brass wetted parts, the PG3T-NL meets requirements for potable water use. A polycarbonate lens provides durability and impact resistance, while clear dial markings ensure quick readability in field environments. This dry (non-liquid filled) model is ideal for stable system conditions without significant pulsation or vibration.

Key Features

• Dial Size: 2" diameter for compact installations
• Connection Type: 1/4" NPT lower mount for vertical panel mounting
• Pressure Range: 0–30 psi
• Wetted Materials: Lead-free brass, suitable for potable water systems
• Lens: Clear polycarbonate for high visibility and impact resistance
• Case Material: Steel
• Fill Type: Dry (non-liquid filled)

Recommended Applications

• Low-pressure water systems
