OEM 4.5 160 PSI Common Rail Pressure Gauge - China Suppliers Factory, Durable Solid Front Phenolic Case Manufacturer, Suppliers

,

Introducing our high-quality pressure gauge, a precision mechanical instrument meticulously engineered for the accurate measurement and local indication of fluid or gas pressure in a variety of industrial, commercial, and process applications. Manufactured in China using durable materials such as stainless steel or brass, our pressure gauges ensure long-term reliability, even in demanding conditions characterized by high vibration, temperature fluctuations, and corrosive environments. Equipped with a Bourdon tube sensing element, our gauges effectively convert pressure into mechanical displacement, clearly displayed via a calibrated dial and pointer.

,

Our pressure gauges are available in a range of dial sizes, pressure ranges, and connection types, allowing for customization that meets diverse system requirements. As trusted suppliers in the industry, we serve multiple sectors including oil & gas, chemical processing, water treatment, HVAC, power generation, and manufacturing. Additionally, optional features such as glycerin or silicone fluid filling for damping, overpressure protection, adjustable zero mechanisms, and adherence to international standards (e.g., EN 837, ASME B40.100) enhance the functionality of our products.

,

Designed for effortless installation and maintenance, our pressure gauge offers stable performance, excellent readability, and an extended service life, making it an essential component for safe and efficient system monitoring. As a reputable factory, we are committed to delivering pressure gauges that meet your specific needs while upholding the highest quality standards.

Core Features and Advantages
Durable Structure and Protection Design The case is made of high-quality Phenolic material with rust-proof treatment, suitable for damp, dusty, and mildly chemically corrosive environments. Chrome-plated options are available, further enhancing the appearance and protection level. The glass and polycarbonate (PC) options for the lens provide strong impact resistance, suitable for situations where mechanical collisions may occur.
High Readability and Precise Indication The white aluminum dial with black scales offers clear contrast, facilitating data reading from a distance or in low light conditions. The pointer, made of aluminum alloy with a black surface treatment, is lightweight and resistant to shaking, ensuring stable and drift-free indication. Both the movement and bourdon tube are made of brass, with a precise transmission structure and sensitive response, guaranteeing consistent measurement over time.
Flexible Installation and Connection Adaptability Supports multiple installation positions (bottom inlet, middle rear inlet, bottom rear inlet) to meet different system layout requirements. Threaded interfaces are compatible with various specifications such as 1/8", 1/4", 3/8", and 1/2", and can be provided with PT (BSPT/ZG), BSP (G/PF), NPT, and other thread standards according to customer needs, greatly enhancing system integration flexibility.
Wide Range of Applications with Multiple Sizes The dial size covers seven specifications ranging from 40mm (1.5") to 200mm (8"), suitable for embedding into compact equipment panels or using on large units or remote monitoring dashboards. This meets the full range of pressure monitoring needs, from fine pneumatic control to heavy-duty hydraulic systems.

Frequently Asked Questions
Q What thread standards are compatible with this pressure gauge?
This pressure gauge supports a wide range of thread standards including PT (BSPT/ZG), BSP (G/PF), and NPT, with connection sizes available in 1/8", 1/4", 3/8", and 1/2". Custom thread specifications can be provided upon request to ensure compatibility with your existing system.
Q What material is the case and why is Phenolic used?
The case is made of high-quality Phenolic material, which offers excellent resistance to moisture, dust, and mild chemical corrosion. Phenolic is a robust thermoset plastic that maintains structural integrity under varying temperatures and environmental conditions, making it ideal for industrial applications. Chrome-plated options are also available for enhanced protection and aesthetics.
Q What dial sizes are available for this pressure gauge?
The dial size ranges across seven specifications from 40mm (1.5") up to 200mm (8"). This variety accommodates everything from compact panel-mounted installations to large industrial units and remote monitoring dashboards, covering the full spectrum of pressure monitoring requirements.
Q What installation positions are supported?
The gauge supports multiple installation positions including bottom inlet, middle rear inlet, and bottom rear inlet. This flexibility allows it to be integrated into a wide variety of system layouts without requiring additional adapters or modifications.
Q Is this pressure gauge suitable for use in chemically corrosive environments?
Yes. The Phenolic case provides resistance to mild chemical corrosion, and the stainless steel connection and bourdon tube further enhance durability in corrosive conditions. For highly aggressive chemical environments, please consult with our technical team to confirm the appropriate material configuration.
Q What makes the dial easy to read, and how accurate is the pointer?
The white aluminum dial with black graduations provides high-contrast visibility, making it easy to read from a distance or in low-light conditions. The aluminum alloy pointer features a black surface finish that reduces glare and minimizes vibration-induced drift, ensuring stable and accurate readings over extended periods of use.
