Step down fittings allow the use of a larger screw on fitting size eg. #8 to scale down to a #6 hose size. These can be used in situations such as bulkhead fitting reduction eg. a 4 way bulkhead fitting may have two size #10 heater ports, one size #10 suction port and a #8 Liquid line port. Most liquid lines are size #6 so you will need to reduce your original #8 down to a #6 hose, this is where these fittings come in handy. |
