Product Overview

This Tube Fitting Brass is a precision-engineered component designed to securely connect tubing systems in industrial and commercial applications. It provides reliable fluid or gas transfer for air, water, and certain chemicals under controlled conditions. The fitting ensures stable performance in environments where exposure to moisture or temperature fluctuations is common, making it ideal for use in pipelines, ventilation systems, and process equipment.

Construction and Materials

The main body of the fitting is constructed entirely from brass, specifically a special alloy that offers significantly improved corrosion resistance to water. This material selection enhances long-term durability and performance in wet environments. The seal material uses low concentration ozone-resistant HNBR or FKM rubber, ensuring compatibility with certain chemical flows—though some variants are only suitable for use within the flow path.

Configuration and Connections

The fitting features a direct connection design without requiring any connecting sleeve. This eliminates risks associated with missing or lost sleeves during installation. It is available in multiple configurations including both male and female tapered pipe threads, such as R1/8, R1/4, R3/8, and R1/2 for male ends, and Rc1/8, Rc1/4, Rc3/8, and Rc1/2 for female ends. These threaded interfaces allow compatibility with a wide range of standard tube systems.

Operating Characteristics

The fitting is rated to operate under a maximum vacuum of -101.3 kPa and supports fluid media including air, water, and other chemicals under conditional use. The operating temperature range is limited only by the tube’s own specifications (no freezing conditions). Maximum operating pressure is determined by the tube itself, not the fitting, ensuring safe performance within system constraints.

Sizes and Options

Available in a range of standard sizes from φ4xφ2.5 to φ16xφ13, with internal and external diameters precisely matched for secure fitment. The full size list includes: φ4xφ2.5, φ6xφ4, φ8xφ5, φ8xφ6, φ10xφ6.5, φ10xφ7.5, φ12xφ8, φ12xφ9, φ16xφ11, and φ16xφ13. All fittings are designed for use in high-temperature and spatter-prone environments, as well as applications requiring static control.

Installation and Integration

Installation is straightforward—no lubrication is required during assembly due to the non-grease, oil-free design. The fitting integrates directly into existing systems using standard tapered pipe threads (R or Rc), with no additional components needed. This makes it easy to retrofit or replace in both new installations and maintenance scenarios.
