^^ use a silicon as glue.
on the left is a 1/2 inch thread ...jus about everything can attach to this
the other right end is a 13mm/12.4mm insert for the average garden hose
common as muck!
IMO: if this for a sump/rez? drill a 12mm hole and screw this in with hose attached
maybe... sand the face then apply glue? ...maybe
good luck
Yes for res connections, but would rather have a solid seal connection with nut and ring. The stop tap connectors come with the fittings I want but they are more expensive and the tap is not required for purpose. They can also be a source of leak under pressure or orientation, you dunno the quality until you use it so not risking it. Was hoping a full set is available with connector -tap ;[.
