Hijacker Camper Jack ORing Rebuild Parts List

Over the weekend we were rebuilding the Hijacker Camper Jacks on our camper. Since Hijacker has gotten out of the camper jack business, the rebuild kits are tough to find. We were in NAPA (Canada) and managed to size replacement o-rings that seem to do the trick.

The product codes for the replacement o-rings are:

NAPA Part Number Hijacker Part # Description
DYN-54112 HJ-111 STATIC O-RINGS 1/2″ ID
DYN-54111 HJ-112 CHECK VALVE / PAC END O-RING 7/16″ ID
DYN-54008 HJ-114 RELEASE VALVE O-RING 3/16″ ID
DYN-54011 HJ-121 PLUNGER O-RING 5/16″ ID
