Harris 25C-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 #H25C-RK will repair all oxygen, acetylene, and fuel Harris 25 Series regulators with an encapsulated valve seat.  Kit includes the following original Harris parts: Encapsulated Valve Seat #9100601,  Diaphragm #9100146, O-Ring #9002860 and Slip Ring #9001230.

This repair kit will also repair the newer Harris Acetylene models 25GX-15-300 & 25GX-15-510.
