All PVC fittings can be manufactured with:
• E-Z Flange Jr. with Barrel Clamp – 6” to 24” Diameter
• E-Z Flange with Barrel Clamp – 26” to 96” Diameter
• Standard Spiral Slip Connector
45 Degree Standing Seam Angles must be sealed at the transverse connection to prevent air leakage and to keep dirt and sand out of the duct system. For this, PVC Tape is recommended, with its superior adhesive qualities that won’t diminish in extreme hot or cold conditions. PVC Duct Sealer No. 8 is also recommended, as it’s a flexible, self-curing air pressure sealant. Apply from one-gallon cans by brush or using a cartridge package. Approximate coverage is 375 linear feet per gallon at a 1/4” bead.
Standing Seam Elbows and Angles
Standing Seam fittings work well for medium pressure applications. These are available from 8” through 60” diameters and fabricated as heavy as 16 gauge. Other diameters and throat radiuses are available.
Full Sweep Standing Seam Elbows
8”-30” will be a 5 gore one-piece standard throat construction. 32” and larger in diameter (1.5 x CL) 90 degree full sweep elbows are fabricated using two 45 degree angles connected with an E-Z flange and barrel clamp.
