Sioux Chief ELL 1-1/2" PVC 45° Slip Joint Elbow

Sioux Chief 1-1/2" PVC 45° Slip Joint Elbow

The Sioux Chief 1-1/2" PVC 45° Slip Joint Elbow is a tubular waste fitting used to change direction in trap arm and drain-line assemblies behind fixtures such as sinks and lavatories. Sized for 1-1/2" tubular waste lines, this PVC elbow uses a slip joint connection so it seats against the mating tube with a slip nut and washer rather than a solvent-welded joint, letting a plumber align, adjust, and disassemble the fitting during rough-in and service work without cutting or re-gluing pipe. The 45° bend is a common angle for offsetting a trap arm around framing, a wall stub-out, or another fixture connection, and it is sized to work alongside other 1-1/2" tubular waste components such as trap adapters, slip nuts, and tailpieces already in use on a fixture drain run. Because it is a slip-style tubular fitting rather than a solvent-weld DWV fitting, it is intended for exposed or serviceable waste connections, not for permanently cemented drain, waste, and vent piping runs.

Key Features

• Trade Size: 1-1/2" fitting sized for tubular waste and trap arm connections on standard fixture drains.
• Bend Angle: 45° elbow for offsetting drain and waste-line runs around framing, obstructions, or fixture stub-outs where a straight run will not line up.
• Slip Joint Connection: Slip-style joint mates with tubular waste components using a slip nut and washer, allowing the fitting to be positioned, tightened, and later taken apart for cleaning or repair without solvent welding.
• PVC Construction: PVC body resists corrosion and chemical attack from typical drain-line waste, standing up to continuous under-fixture use.
• Rough-In Fitting: Designed for behind-the-wall and under-fixture tubular drain assembly rather than finished, visible plumbing.
• Compatible Assembly: Works alongside other 1-1/2" slip-joint tubular waste parts, such as trap arms, tailpieces, and slip nuts, in a single fixture drain run.

Why Sioux Chief?

Sioux Chief is a long-standing name in rough-in plumbing supply, and this 1-1/2" PVC 45° slip joint elbow reflects that trade focus: a straightforward PVC fitting built for tubular waste assemblies where a slip connection and a 45° offset are exactly what the installation calls for. Its PVC construction and slip joint design make it a practical choice for plumbers stocking dependable tubular drain fittings for new construction, remodel work, and service calls where a trap arm or waste line needs to be reworked without cutting into cemented DWV piping. Keeping a 1-1/2" 45° slip joint elbow on the truck covers a common fixture-drain offset without a special-order wait.
