The Smith-Blair 442 OMNI Long Sleeve Coupling is designed for straight and reducing transitions. These cast couplings join plain end pipes with different O.D.s by changing followers and gaskets that can be mixed and matched on the same size nominal sleeve. Most couplings are stab fit, making installation a breeze with no disassembly required. Up to 2.4" of range with a single coupling reduces the need for large coupling inventories, and one sleeve per nominal pipe size takes the guess work out of deciding which sleeve size to choose.

The 442 OMNI coupling is constructed with heavy cast Ductile Iron parts for long life. The sleeve is made from Ductile Iron ASTM A536 with ends that have smooth inside taper for uniform gasket seating. Gaskets are Nitrile (Buna N) certified to NSF/ANSI 61-G, compounded to produce superior storage and performance characteristics while resisting water, acids, alkalies, most (aliphatic) hydrocarbon fluids and other chemicals. Follower flanges are Ductile Iron ASTM A536, designed for high strength to weight ratio. Bolts and nuts are high strength low alloy Steel bolts with heavy, semi-finished hexagon nuts to AWWA C219 (ANSI A21.11) with Stainless Steel optional. The coupling features Flexi-Coat® Fusion-Bonded Epoxy Finish.

The 442 OMNI coupling is rated for working pressure up to 250 PSI. It is designed for use with Steel, Cast Iron, Asbestos Cement, PVC and other pipe materials. For other pipe materials, please contact Smith-Blair Engineering. The coupling meets applicable AWWA C219 Standards and is available in sizes 2½, 4, 6, 8, 10, 12, 14, and 16 inches. Flanges are color coded by pipe type: Red for standard pipe size O.D.; blue for ductile O.D.; and gray for Asbestos Cement O.D. Gaskets and flanges are permanently marked with a part number and range to facilitate proper selection, and sleeves are available in a variety of lengths with custom length Steel sleeves available for special applications.

This product does not restrain pipe movement. Proper anchoring is required to prevent pipe pullout. Failure to anchor or improper anchoring can result in dangerous pipe content escape, property damage, serious injury, or death. Users must read the product installation instructions prior to installing this product.
