THIS KIT CONTAINS 36 OF THE MOST POPULAR SIZE “Parback®” STYLE DISHED CROSS-SECTION BACK-UP RINGS. THERE ARE 293 PIECES OF MOLDED 90 DUROMETER BUNA-N RUBBER RINGS IN THE KIT. THEY STREACH FOR INSTALLATION, AND QUICKLY RETURN TO THE ORIGINAL SIZE. THE DASH SIZE CORRESPONDS DIRECTLY WITH THE O-RING DASH SIZE. BACK-UP RINGS ADD O-RING SUPPORT AND LET THE O-RING OPERATE AT A LITTLE HIGHER PRESSURE. REMEMBER, THE BACK-UP RING ALWAYS MOUNTS AWAY FROM THE PRESSURE.
