These bolt kits are designed to bolt together ASA 4.5 or ASA 5.0 (ANSI 1 or ANSI 1.5) flanges. The kits consist of four 9/16-12 x 2" long bolts and nuts, flat and lock washers, all made of stainless steel. These kits work with both grooved or non-grooved flanges. Grooved flanges require an additional elastomer rubber O-Ring. We recommend using thread anti-seize lubricant on all vacuum fitting bolts. Bolt Kit Includes:4 Bolts, 9/16-12 Thread x 2 inch Long4 Nuts, 9/16-124 Lock Washers8 Flat Washers ASA flanges are available with a smooth or grooved face, rotatable or non-rotatable, bored or non-bored, and are named for the outer diameter of the flange, from 4.25 to 19 inches. The ANSI name for the same flange size corresponds to the nominal tubing size that can be welded to it, and ranges from 1 to 12 inches in diameter.

These bolt kits are designed to bolt together ASA 6.0 or ASA 7.5 (ANSI 2 or ANSI 3) flanges. The kits consist of four 5/8-11 x 2" long bolts and nuts, flat and lock washers, all made of stainless steel. These kits work with both grooved or non-grooved flanges. Grooved flanges require an additional elastomer rubber O-Ring. We recommend using thread anti-seize lubricant on all vacuum fitting bolts. Bolt Kit Includes:4 Bolts, 5/8-11 Thread x 2 inch Long4 Nuts, 5/8-114 Lock Washers8 Flat Washers ASA flanges are available with a smooth or grooved face, rotatable or non-rotatable, bored or non-bored, and are named for the outer diameter of the flange, from 4.25 to 19 inches.

These bolt kits are designed to bolt together ASA 11 or ASA 13.5 (ANSI 6 or ANSI 8) flanges. The kits consist of eight 3/4-10 x 2.25" long bolts and nuts, flat and lock washers, all made of stainless steel. These kits work with both grooved or non-grooved flanges. Grooved flanges require an additional elastomer rubber O-Ring. We recommend using thread anti-seize lubricant on all vacuum fitting bolts. Bolt Kit Includes:8 Bolts, 3/4-10 Thread x 2.25 inch Long8 Nuts, 3/4-108 Lock Washers16 Flat Washers ASA / ANSI flanges come in smooth or grooved flanges, bored or non bored, rotatable or non rotatable, and adapters to other flange types. With tubing sizes ranging from 1 in. to 12 in. diameter and outer diameters from 4.25 in. to 19 in. The Sizes of ASA are from 1 in. to 12 in. The two flanges that will mate can be two alike smooth flange faces or two unlike, one smooth face and one groove face. The flanges are mated together with nuts, bolts and washers.
