More About #150 Fittings

Class 150, or #150 fittings are categorized under low pressure fittings and are made in accordance with ​ASTM A351 standard. These fittings are commonly used to extend system pipeline and regulate low pressure fluid and gas. The maximum working pressure is up to 150 PSI. As such, they are the top selection when it comes to non-critical and low-cost applications in the water, oil, and gas (WOG) system. #150 fittings are threaded which provides a tighter seal upon installation. Do keep note that the connection needs to correspond to each other. The material used is stainless steel 316. This steel grade contains molybdenum (Mo), which increases the chemical and corrosion resistance as compared to the standard 304 grade.

• The threaded ends ease installation and provide a tighter connection. Welding is not required.
• Conform to ASTM A351 CF8M/316 grade. Made of stainless steel 316 for better resistance against corrosion and rust.
• Ideal for low pressure, non-critical and low-cost applications as it has a working pressure up to 150 PSI.

How to Connect #150 Fittings?

1. To install a class 150 fitting, use a Teflon tape/plumber’s tape to thread the male end to form a tighter seal.
2. Remove any excess tape and tighten the joints.
3. Do avoid excessive screwing as it may damage the pipe or the fitting.
4. Finally, ensure that the alignment and size of the fitting and pipe are the same when making connection.
