What This Strainer Does

The BELL & GOSSETT 415C is a 1/2-inch Y-pattern strainer built from cast iron for industrial piping systems. It removes debris from oil, steam or water lines to protect downstream equipment. The unit is rated for 400 psi at 100 degrees F and 150 psi at 400 degrees F, making it suitable for high-pressure service. The stainless-steel screen has a 0.0331-inch mesh opening and is included with the housing.

Verify Your Piping Before Ordering

Confirm the line uses 1/2-inch female NPT threads on both sides so the strainer connects directly without adapters. The body measures 3 1/4 inches long and 2 1/8 inches high; ensure that space exists in the run. The blow-off port is 1/4 inch NPT, so plan a matching valve or plug for cleaning. The 1.75-pound weight is light enough for standard pipe supports but check hanger spacing for the full assembly.

Cast Iron Body and Daily Implications

The cast iron housing handles the rated pressure and temperature range without deformation. Female NPT threads on both ports mean the strainer screws onto male pipe ends and stays oriented by the piping itself. The 1/4-inch blow-off port lets you flush the screen without breaking the line, reducing downtime. Stainless-steel mesh resists corrosion from water, oil and steam, so cleaning intervals stay predictable.

Questions about this item

Does the 415C Y strainer ship with the 0.0331 in mesh stainless steel screen already installed or must it be purchased separately?

The supplier description confirms the screen is included with the strainer, so no separate screen purchase is required.

How do I decide between the 400 psi @ 100 °F and 400 psi @ 150 °F ratings for my system?

Both ratings show the same 400 psi maximum pressure; the temperature figures simply indicate the pressure holds at 100 °F and at 150 °F, so choose based on your actual operating temperature.

What does the 400 psi / 400 °F headline rating mean once the strainer is piped into a live steam or water line?

It means the cast iron body and NPT connections are rated to withstand 400 psi continuously at temperatures up to 400 °F, provided the piping and gaskets are also rated for those conditions.
