My Buying Guide on ‘1 1/4 Brass Union’

As a plumber with years of experience, I have come across various types of fittings and unions. One of the most commonly used and reliable unions is the 1 1/4 brass union. It is suitable for a wide range of plumbing applications and offers great durability and strength. In this buying guide, I will share my personal experience and provide you with all the necessary information to help you make an informed decision when purchasing a 1 1/4 brass union.

What is a 1 1/4 Brass Union?

A brass union is a type of pipe fitting that allows for easy disconnection and reconnection of two pipes or tubes. It consists of two threaded ends with a nut in the middle that can be tightened or loosened to join or separate the pipes. The 1 1/4 brass union, as the name suggests, has a thread size of 1 1/4 inches, making it suitable for connecting pipes with the same diameter.

Material

The material used in making any plumbing fitting is crucial as it determines its strength and durability. The 1 1/4 brass union is made from high-quality brass, which is a combination of copper and zinc. This material makes it resistant to corrosion, rusting, and high temperatures, making it ideal for both indoor and outdoor plumbing applications.

Size

The size of the union should match the diameter of your pipes. The standard size for a 1 1/4 brass union is 2 inches in length. However, there are variations in length depending on the manufacturer. It is essential to measure your pipes’ diameter accurately before purchasing to ensure a proper fit.

Pressure Rating

The pressure rating refers to how much pressure the union can withstand without breaking or leaking. The higher the pressure rating, the more suitable it is for high-pressure plumbing systems. The average pressure rating for a 1 1/4 brass union ranges from 150-300 PSI (pounds per square inch). If you are unsure about your plumbing system’s pressure, it is always best to choose a higher pressure rating for added safety.

Brand Reputation

When buying any plumbing fitting, it is essential to consider the brand’s reputation to ensure you get a reliable and high-quality product. Some well-known brands that manufacture top-quality brass unions include Mueller Industries Inc., SharkBite, NIBCO, etc.

Price

The price of a 1 1/4 brass union can vary depending on its quality and brand. While it may be tempting to go for cheaper options, remember that cheap products may compromise on quality and durability. It is always better to invest in a slightly pricier but high-quality product that will last longer.

Certifications

Certifications such as ANSI (American National Standards Institute) or NSF (National Sanitation Foundation) indicate that the product has met specific standards set by these organizations regarding material quality, safety standards, etc. When purchasing a brass union, look out for these certifications as they assure you of its quality.

In Conclusion

A good quality brass union like the one described above can last for many years without requiring any maintenance or replacement. With this buying guide in hand, I hope you can make an informed decision when purchasing your next 1-14 inch brass union for your plumbing needs.
