All Stainless Steel Pressure Gauge

-- Steady & Reliable Manufacturer --

Product Overview

Our All Stainless Steel Pressure Gauges feature wetted parts, case, and bezel manufactured entirely from AISI 304 or 316L stainless steel, making them the premier choice for aggressive chemical, food processing, pharmaceutical, and marine environments. Unlike standard gauges with brass or copper internal components, the all-SS construction eliminates galvanic corrosion, complies with hygiene regulations, and withstands exposure to corrosive cleaning agents and humid outdoor conditions without degradation over decades of service.

Key Features

Entire wetted path in SS 316L ensures compatibility with a broad range of corrosive media and cleaning chemicals.
Electropolished interior option (Ra ≤ 0.4 μm) meets hygienic standards for food and pharmaceutical applications.
Available with glycerin or silicone oil fill for vibration-prone installations.

Typical Use Cases

Chemical Plants: Monitoring acids, alkalis, and solvents that would corrode brass-wetted gauges.
Food & Beverage: CIP-compatible pressure monitoring on breweries, dairies, and bottling lines.
Pharmaceutical Manufacturing: GMP-compliant pressure indication on reactors and clean utilities.
Marine Applications: Saltwater-resistant instrumentation on vessels and offshore platforms.
Outdoor Installations: Weather-resistant monitoring in rain, humidity, and UV-exposed environments.

Competitive Benefits

Superior Corrosion Resistance: 316L SS wetted parts resist chloride pitting and stress corrosion cracking far better than copper alloy alternatives.
Hygienic Design Compliance: Electropolished wetted surfaces and crevice-free designs meet FDA, 3-A, and EHEDG hygienic guidelines.
Long Service Life: Eliminates the dezincification and selective leaching that degrades brass-wetted gauges in high-chloride water systems.
Aesthetic Durability: The brushed SS case maintains a professional appearance throughout its service life, resisting rust staining in wet environments.
One-Stop Sourcing: Available in standard, liquid-filled, diaphragm-sealed, and electric contact configurations — all in full stainless construction.

Payment and Shipping Details

We accept T/T, L/C, and Western Union for international orders. Standard shipping terms are FOB Ningbo/Shanghai or CIF destination port. Standard catalog models ship within 7–10 working days; electropolished or Tri-Clamp connection variants require 15–20 working days. All gauges are individually bubble-wrap packed and placed in export cartons with foam inserts for damage-free delivery.
