Replacement hardware for Smith-Blair OMNI couplings (441, 442), end caps (482) and the 912 OMNI flanged coupling adapter. Most 2 to 8 in OMNI couplings take 5/8 x 8 in oval neck bolts; 10 to 16 in take 5/8 x 9 in, with longer bolts on reducing and long-sleeve builds. The 912 uses ductile iron cross bolts and tee bolts plus flange bolts or studs by size.
Pick the type and size, then the finish; the part number shows in the last option. Bolt and nut counts per coupling are on the Smith-Blair selection chart (one nut per bolt on OMNI couplings); the 912 takes three nuts per stud and one per flange bolt. Spring washers are for approved HDPE products, two per bolt.
Included: Low-cost items are sold in packs (2 to 50 pieces); the pack size shows in the last option with the part number. Coupling bolt counts are on the Smith-Blair datasheet for each style.
