Copper Bonnet

Convertible Port Interface:
Fundamental difference: This is the core and unique value of Copper Bonnet. It is neither a simple sealing plug (Plug), nor a simple connecting connector body (Adapter), nor a gasket (Gasket), but an intelligent fusion of the two:
As a blind cover (Plug Mode): When its NPT end is screwed into the equipment port and the SAE 45° end is not connected to any pipe, it is equivalent to an extremely strong pipe plug with its port seal.
As a connector (Adapter Mode): When its NPT end is fixed on the equipment port and the SAE 45° end is connected to the pipe, it becomes a standard connector that converts the internal threaded port of the equipment to an SAE 45° external cone connector.
Mode conversion: After installing Bonnet on the equipment port, there is no need to disassemble it. Just connect or disconnect the pipe at its SAE 45° end when needed to seamlessly switch between the two functional states of "sealed blind cover" and "fluid channel interface".

Spare ports/test ports on hydraulic manifolds/manifolds: Pre-installed Bonnet as a blind cap, connect pressure gauges, sensors, flushing circuits or future expansion piping when needed.
Drain ports/case pressure test ports on pumps and motors: Normally closed, open for maintenance or testing.
Tank cleaning ports/level gauge interfaces: Pre-installed blind caps, connect hoses or sight glasses for cleaning or inspection.
High-point exhaust ports on the system: Install Bonnet, which acts as a blind cap after initial exhaust, and can be reconnected to an exhaust valve for subsequent maintenance.
Port seals that require ultimate ruggedness: Replace standard Flared Plug or NPT Plug, providing greater resistance to vibration and shock.
Simplify equipment design: Equipment manufacturers only need to provide NPT ports, which can be compatible with SAE 45° piping systems through Bonnet.
