Unitherm FPW4212 Flange Jacket for Straight Sections

The Unitherm FPW4212 is a flange jacket designed for straight pipe sections with tee or wye fittings. It uses mineral wool insulation with a silicone facing material and a lacing anchor and wire fastening system. The jacket fits pipe circumferences between 31 in and 38 in and suits industrial maintenance teams insulating hot piping systems.

Check Pipe Circumference and Voltage Before Ordering

Verify that the pipe circumference falls within the 31 in to 38 in range so the jacket secures correctly. Confirm the operating voltage at the installation site matches 120V for the integrated heating cable. Ensure the flange type is compatible with straight sections using tee or wye fittings before purchase.

Sustained Load Behaviour Up to 200 Degrees F

The mineral wool insulation maintains an R value of 0.48 under continuous exposure to maximum ambient temperatures of 200 Degrees F. The 3 in thickness and silicone facing resist thermal degradation during prolonged heating cycles. The 18 AWG cable gauge supports steady current flow without overheating during extended operation.
