Port Body / Fitting for Pressure Test Ports - Specifications and Verification

Product Specifications

Technical details and manufacturing context for Port Body / Fitting

Definition

The port body/fitting is the primary structural element of a pressure test port. It serves as the housing that contains internal components and provides a standardized connection interface for attaching test equipment. This component ensures proper sealing, alignment, and mechanical integrity during pressure testing operations. It is designed to connect to the system under test, allowing pressure to be applied or measured while maintaining system integrity and preventing leaks. The port body is available in materials such as stainless steel, brass, and carbon steel, with material grade 316L specified for corrosion resistance in harsh media. Key parameters include nominal diameter (DN15–DN50 per ISO 6708), operating pressure (1.0–1.6 MPa), test pressure (1.5–2.4 MPa), operating temperature (-40 to 85°C), thread type (G1/4–G1 per ISO 228-1), surface roughness (Ra 0.8–1.6 μm per ISO 1302), weight (0.15–0.35 kg), leakage rate (≤0.01 mL/min), and seal material (FKM per ASTM D2000). These values are directory reference ranges and must be confirmed for the specific model and application. The port body is a component used in machinery and equipment manufacturing, particularly in pressure testing systems. It is not a standalone product but part of a larger assembly. For procurement, verify that the actual product meets the required standards and specifications. Always consult the legal manufacturer or supplier for model-specific data and compliance.

Working Principle

The port body provides a sealed chamber that connects to the system being tested. When test equipment is attached to the fitting interface, pressure can be applied or measured through the port while maintaining system integrity and preventing leaks. The internal components, such as seals and valves, are housed within the body, and the standardized thread interface ensures a secure connection. The operating pressure range and test pressure are critical for ensuring the body can withstand the forces during testing. The seal material (FKM) is resistant to oils and fuels, and the surface finish (Ra 0.8–1.6 μm) reduces particle retention. The leakage rate must be ≤0.01 mL/min to ensure no loss of pressure. Proper installation and torque are essential to maintain sealing and alignment.
