Harris 25-RK

The 25 series has been updated over the years.  Older Harris 25 models have a seat assemble that consist of several individual parts.  The newer Harris 25 models use an encapsulated seat assemble (Cartridge).    Also, some of the older Harris 25 models have a fine thread 1/2-27 inlet connection, not a 1/4 NPT  which is standard  on all newer models.

Please verify which Harris 25 series regulator you have before purchasing inlet connection or repair kit.

Our repair kit #H25-RK will repair all older oxygen, acetylene, and fuel Harris 25 Series regulators. These older 25 series regulators can be identify by the use of 5 individual parts in the seat assemble (Part #10-14 in the drawing to the left).  Kit includes the following original Harris parts: Valve Seat #9100774,  Diaphragm #9100146 and Slip Ring #9001230.

This repair kit also repairs Harris model 25-15 and 25-100 regulators.
