| BIJUR LUBRICATION FITTINGS ① BRAZE (IN BRASS PIPE-SOLDER) SMALL 1/4" SCREW. LARGE 7/16" SCREW. NEW BIJUR DRIP PLUG similar to this screw in outside dimensions. Long enough to take two banjos back to back. By this means using double banjos we can have four pipe junctions and a drip plug with only one fitting. Present drip plugs cause excessive loop of pipe (as A), or projection B. Also if taper thread C is tightened violently in an attempt to square up an “L” or “T” type plug the contraction may jamb the non-return valve D.{John DeLooze - Company Secretary} Oy | ||
