These are two marine bronze hose adapters, one made by Apollo/Conbraco and one made by Groco. Note the length of the hose adapter portion. There is plenty of space to fit two hose clamps.


It should go without saying that when buying hose adapters, for below waterline use, that you always buy marine bronze or Marelon and not yellow brass or PVC. While yellow brass may be fine for the domestic plumbing aboard, or certain fuel fittings, it is not ok for use below the waterline.


Always make sure your hose adapters will fit two hose clamps..
