In plumbing, the terms "Street 90" and "Standard 90" refer to types of fittings used to change the direction of pipes. Here's a breakdown of the differences:
-
Standard 90 (also called a "Regular 90" or "90-degree elbow"):
- This fitting has two ends that are the same size and shape, allowing for a 90-degree turn in the pipe's direction.
- It is typically used to connect two segments of pipe that are running perpendicular to each other.
- The ends are usually both male or both female, depending on the type of connection needed.
-
Street 90 (or "Street elbow"):
- A Street 90 also allows for a 90-degree turn in the pipe but has one end that is male (usually smaller) and the other end that is female (larger).
- This allows it to connect to pipes of different sizes or create a connection between a male pipe fitting and another piece of pipe.
- Street elbows are often used when the pipe layout requires connecting to an existing pipe or when there is limited space.
In summary, the main difference lies in the design and connection type: Standard 90s have identical ends, while Street 90s have one end that is sized differently (male) for versatility in connections.
