A BOEING STANDARD FOR AN EXTERNALLY SWAGED UNION - BACU24BS (SIZE)(SIZE) MATERIAL) - BASED ON THE DEUTSCH PERMASWAGE D10282 UNION HAS BEEN DEVELOPED BY BOEING FOR USE ON THE 777 AIRPLANE. THE BACU24BS (SIZE)(SIZE) J UNION (BOTH SIZES THE SAME) AND THE D10282-(SIZE) UNION ARE INTERCHANGEABLE. IN ADDITION, THE BACU24BS (SIZE)(SIZE) D UNION (BOTH SIZES THE SAME) AND D10282D (SIZE) D UNION ARE INTERCHANGEABLE.
THE CORROSION RESISTANT STEEL D10282-(SIZE) AND ALUMINUM D10282D(SIZE) PER-MASWAGE UNIONS ARE IMPROVED REPLACEMENTS FOR THE STANDARD CORROSION RESISTANT STEEL D10036D (SIZE) AND ALUMINUM D10036D (SIZE) UNIONS, RESPECTIVELY. THE D10036 UNIONS ARE FUNCTIONALLY INTERCHANGEABLE WITH THE D10282 UNIONS BUT ARE MORE LIKELY TO DEVELOP LEAKS DURING USE. BOEING DOES NOT RECOMMEND USE OF THE D10036 UNION.
BACU24BS (SIZE)(SIZE) J - (BOTH SIZES THE SAME), BACU24BS (SIZE)(SIZE) D -(BOTH SIZES THE SAME), D10282-(SIZE) AND D10282D (SIZE) UNIONS ARE NOT SHOWN IN DEUTSCH CATALOGS, BUT YOU CAN MAKE AN ORDER DIRECTLY TO DEUTSCH, METAL COMPONENTS DIVISION, 14800 SOUTH FIGUEROA ST., P.O. BOX 61188, LOS ANGELES, CA 90061.
