45°STREET ELBOW；SP×H

Key Characteristics

Angle of Deflection: 45 degrees. This is the angle between the inlet and the outlet of the fitting.

Common Names: It is often simply called a "45-degree elbow" or "45° elbow." The term "1/8" comes from the fact that 45 degrees is one-eighth of a full 360-degree circle.

Material: Made from PVC (Polyvinyl Chloride), which is corrosion-resistant, durable, and commonly used for both pressure and non-pressure applications.

Connections: Available in all standard PVC connection types:

Socket (Slip): The pipe is inserted into the fitting and cemented with PVC solvent glue. This creates a permanent, watertight seal.

Threaded (FIPT or MIPT): Female threads on the inside allow it to be screwed onto a male-threaded pipe. These can be dismantled.

Spigot: A plain end that fits into a socket connection.

Sizes: Comes in the full range of standard PVC pipe sizes, from 1/2" up to 12" or larger for industrial applications.

Primary Functions and Applications

The 1/8 Bend is used in a wide variety of plumbing and fluid-handling scenarios:

Navigating Obstacles: It is perfect for steering a pipe run around corners, beams, or other structures where a 90-degree turn would be too tight or impossible to fit.

Maintaining Flow Efficiency: The 45-degree angle creates less turbulence and friction loss compared to a sharp 90-degree turn. This is especially important in sewer and drain lines (DWV - Drain, Waste, Vent) to prevent clogs and allow waste to flow smoothly.

Gradual Slope Changes: In DWV systems, pipes must be laid with a specific slope for proper drainage. The 1/8 bend is essential for making gradual changes in this slope.

Combining for Custom Angles: By gluing two 45-degree elbows together, you can create a 90-degree turn. This is often done to create an "offset," which is used to bypass a small obstacle while keeping the pipe run parallel to its original path.

Vent Pipe Applications: Used in the venting portion of a plumbing system to direct vent pipes up through walls and roofs.

Installation Tips

Dry Fit First: Always dry-fit the pipes and fittings together (without glue) to ensure the layout is correct and the pieces fit properly.

Use Primer and Cement: For socket connections, always use a PVC primer (usually purple) followed by a PVC solvent cement specifically designed for the type of PVC you are using.

Alignment is Key: After applying cement and pushing the pipe into the fitting, give the fitting a quarter-turn to distribute the cement evenly and make sure it is aligned correctly before the cement sets. The fitting will set quickly.

Follow Codes: For plumbing applications, always follow local building and plumbing codes, which dictate where and how certain fittings can be used.
