Is the Brass Straight End with Choke, Type FR103 compatible with standard UNF-threaded ports and 45° SAE cone fittings?

Yes. The Brass Straight End with Choke, Type FR103 is compatible with standard UNF-threaded ports and 45° SAE cone fittings. It is engineered with an internal UNF thread and an SAE 45° cone to ensure secure, leak-free connections, even under high pressure. Manufactured entirely from high-quality brass, it offers corrosion and wear resistance and includes an integrated throttle valve for precise flow regulation.

Does the Brass Straight End with Choke, Type FR103 require specific hose materials or pressure ratings for safe operation in thermoplastic hose systems?

Brass Straight End with Choke, Type FR103 does not inherently require special hose materials beyond standard thermoplastic hose compatibility, but safe operation depends on matching the hose’s specifications to the fitting’s capabilities. Because FR103 is made of high-quality brass, has an internal UNF thread and SAE 45° cone, and is designed for high-pressure service with an integrated throttle valve, you should ensure the thermoplastic hose used: - Is rated for the system’s maximum working pressure (and any transient/impulse pressures) equal to or exceeding the fitting’s pressure capability. - Has inner diameter and reinforcement suitable for a secure, leak-free connection to the SAE 45° cone and sleeve used with the brass fitting. - Is compatible with the system fluid (hydraulic/pneumatic media) and with brass to avoid chemical degradation or galvanic issues. - Meets relevant temperature ratings for the application so the hose maintains mechanical integrity around the fitting and under flow control. In summary: no uniquely specified hose material is required by FR103, but you must use thermoplastic hoses with appropriate pressure, temperature, fluid compatibility and construction to ensure safe, leak-free operation with this brass fitting.
