The Apeks HP twin adapter allows you to use both a submersible pressure gauge and a transmitter from a first stage that only has a single high pressure port. 

The twin adapter also has the added benefit of allowing the transmitter to rotate 360 degrees, which prevents the transmitter being damaged if a cylinder was to fall over.

The Apeks HP twin adapter utilizes a standard 7/16” thread and is suitable for use on all manufacturers first stages.

• Allows you to use both an SPG and a HP transmitter with a single HP port.
• 360 degree swivel allows the transmitter to move, reducing the chances of breakage and snagging.
• 7/16” UNF HP thread is compatible with all 1st stages.
• Made from chrome plated brass.
