• Temporary or permanent closure of an available female thread on manifolds, fittings, or line components.
• Provision of an access point for future system modifications.
• Maintenance: restoration or securing of a line during interventions and replacements.
• Assemblies and retrofit: orderly management of unused outlets during installation.

Choosing the size 1" allows integration with components of the same size, respecting the specifications of the system in which it is installed.

Operational advantages

Square head: practicality in installation

The square head is a valued solution in system installations because it offers a firm grip with suitable tools, facilitating:

• the clamping in technical spaces where access may be limited;
• the disassembly during inspections and maintenance;
• simpler management on site or onboard, where quick intervention is often a practical requirement.

Brass: component consistent with traditional fittings
