Overview

The Wika 4217250 is a 632.34 series low pressure gauge designed for accurate monitoring of gaseous and liquid media in industrial and process measurement applications. This 4.5" dial gauge features a 0–100 inH2O (0–57 oz./sq.in.) pressure range with 2.5% of span accuracy, making it suitable for compressed air, water, and oil systems. The lower mount 1/4" NPT connection and dual scale marking simplify installation and readability across different measurement units.

Key Features

• Dual Scale Display: Oz./sq.in. and "H2O scales for flexible unit conversion
• Low Pressure Capsule Technology: Optimized for accurate readings in the 15–200 "H2O range
• Brass Wetted Parts: Corrosion-resistant contact surfaces for neutral media including water and compressed air
• Plastic Case: Black fiberglass-reinforced thermoplastic for durability in harsh ambient conditions
• 1/4" NPT Lower Mount: Standard connection for easy integration into existing systems
• New in Box Condition: Factory-sealed, unused unit ready for immediate deployment
