Connections
Precision connection components for reliable gas piping, tubing and equipment integration. PES supplies tube fittings, adaptors, unions, pigtails and flexible hoses for connecting gas sources, pipelines, control systems and point-of-use equipment. Selection depends on gas service, pressure, tubing, equipment, connection type and installation requirements.

System Interface
The Connection Is Part of the System
Connection components are not simply accessories. They form the working interface between gas cylinders, manifolds, regulators, gas panels, pipelines, instruments, equipment and point-of-use assemblies.
Appropriate selection helps align the connection with the gas service and the wider system configuration. PES supports the process from component identification through installation, with each configuration treated as application-dependent.

Regulators to pipelines
Tube, pipe and adaptor interfaces.
Panels to point of use
Organised outlets and flexible connections.
Equipment interfaces
Machine and instrument connections.
Not every installation uses every component. The connection path is configured around the application.
Connection Components
Six Interfaces, One Engineered Approach
From industrial gas connections to gas pipeline fittings, PES helps configure components around the gas, pressure, tubing and equipment interface.
SS Tube & Fittings
Stainless-steel tubing and fitting solutions for gas distribution, instrumentation and equipment connections where appropriate material compatibility and controlled installation are required. Typical use: stainless-steel tubing, instrumentation and panel connections, point-of-use connections.
Brass Fittings
Brass connection components for suitable gas applications, selected according to gas service, pressure and connection requirements. Typical use: threaded connections, equipment interfaces, application-specific selection.
Adaptors
Adaptors used to transition between different connection types, thread configurations or component interfaces within a gas system. Typical use: connection transitions, equipment and panel interfaces, configuration-dependent.
Unions
Union fittings that allow suitable sections of tubing or piping to be connected and, where appropriate, separated for installation or maintenance. Typical use: removable connections, maintenance access, panel and equipment integration.
Copper Pigtails
Flexible or semi-flexible copper connection assemblies used for suitable gas-cylinder and manifold applications. Typical use: cylinder connections, manifold connections, gas-source interface.
Flexible Hoses
Flexible hose assemblies designed for suitable gas-transfer applications where movement, vibration or equipment connection requires flexibility. Typical use: equipment connections, vibration accommodation, application-specific assembly.
Selection Framework
Selected for the Gas and the Application
Connection selection forms part of the complete gas-system design. Each interface should be reviewed against the surrounding components and installation conditions.
Gas Compatibility
Materials and construction should be suitable for the gas service.
Pressure Requirements
Components should be selected according to system pressure requirements.
Connection Type
Threads, tubing and equipment interfaces must be compatible.
Installation & Integration
Routing, access, vibration, maintenance and surrounding regulators, valves, panels and pipelines all influence selection.
Complete System Integration
Every Connection Has a Role
PES supplies connection components that integrate with the broader gas-system architecture, helping connect individual components into a complete installation. From standard tube fittings and adaptors to pigtails and flexible hose assemblies, PES can help configure connection components around the gas, equipment and installation requirements.
