Senex Aeromax Air Injector Cap Replacement - White

3D printed replacement cap for Senex air injectors.

White

Standard length threaded version
Thread approx 6mm long

If the internal body thread starts approximately 5-6mm deep, this is NOT the version required. 
The correct injector bodies have a thread starting 2mm deep 

This cap will not suit injector bodies with internal threads starting 5mm deep

Threads into brass injector body

Senex spa bath air injector cap - threaded with 4 channels.
25.7mm diameter cap, 12mm diameter thread, 6mm thread length.
(the same injector cap was also made with approx double the thread length)

NB - take care starting the thread - easily cross threaded due to the thread being so fine
