1BT Inch Thread Through ISO1179

1. Product Overview

The 1BT is a BSPP/BSPT dual-male-thread straight-through coupling designed for high-pressure inch-based fluid systems. Its core function is to enable straight-through connections between different types of inch pipelines, solving the connection challenge between BSPP parallel thread and BSPT taper thread pipelines. It can also be used for port sealing and pipeline expansion during equipment maintenance, providing a stable, leak-proof straight connection solution for industrial fluid systems.

2. Core Design Advantages

The product adopts a differentiated dual-end thread design, combining the sealing performance advantages of both thread types: One end is a BSPP parallel male thread with an integrated 60° seat, forming a high-pressure-resistant sealing interface when connected to matching fittings, adapting to system pressure fluctuations and eliminating leakage. The other end is a BSPT taper male thread, whose tapered structure creates a self-sealing effect during assembly, requiring no additional gaskets for leak-proof connections in most scenarios. This greatly simplifies on-site assembly and improves long-term sealing reliability.

3. Standard Compliance & Performance Parameters

Compliant with three international standards: ISO 7-1, BS 5200 and ISO 8434-6, the coupling ensures universal compatibility and interchangeability with mainstream inch pipeline components, meeting the needs of cross-border industrial projects. With a maximum working pressure of 420 bar (6000 PSI), it can meet the working conditions of medium-to-high pressure hydraulic and oil/gas systems. Precision-machined from high-strength carbon steel, its rugged construction resists hydraulic oil corrosion and long-term high-pressure impact, extending service life and reducing maintenance downtime costs.

4. Specification Adaptation & Application Scenarios

Available in mainstream BSP inch thread sizes, the coupling adapts to straight-through connection needs from miniature automation oil circuits to large industrial main pipelines, offering strong versatility and easy selection. Typical applications include:

Construction Machinery Hydraulic Systems: Connecting different types of inch pipelines on excavators, loaders, cranes and other equipment, adapting to complex pipeline layouts inside machinery

Oil & Gas Processing Lines: High-pressure pipeline straight-through connections for oil and gas processing facilities, leak-proof and corrosion-resistant to ensure safe fluid transmission

Industrial Hydraulic Station Retrofits: Upgrading inch pipeline connections on old equipment, enabling connections between different thread pipelines without full disassembly, reducing downtime for renovation

Marine & Offshore Hydraulic Circuits: Pipeline connections for deck machinery and steering systems, suitable for humid and salt spray environments with impact and corrosion resistance

Automated Production Line Hydraulic Systems: Straight-through connections for internal oil circuits of industrial equipment, gasket-free design simplifies installation and adapts to mass production scenarios
