Valve insulation heater for tee and wye fittings

The Unitherm FPV1812 jacket fits tee and wye fittings with circumferences between 7 in and 13 in. A silicone cover and mineral wool insulation protect the valve in ambient temperatures up to 200 Degrees F. The unit operates on 120V power.

Lacing anchor and wire fastening system

Wrap the 18 in by 12 in cover around the fitting and secure it with the integrated lacing anchors and wire. The 3 in thickness adds bulk, so confirm clearance around adjacent pipework before installation. The flexible silicone jacket conforms to irregular shapes without tools.

Sustained heat retention at 0.48 R-value

The mineral wool core maintains its 0.48 R-value during continuous 120V operation, limiting heat loss over long duty cycles. The silicone cover resists degradation at the rated 200 Degrees F ambient limit. Performance stays stable without the decay seen in short-cycle tests.

Questions about this item

How can I confirm the FPV1812 is heating properly after installation?

Check that the surface temperature does not exceed 200 Degrees F and that the lacing anchor wire fastenings remain snug around the tee or wye fitting.

What comes with the FPV1812 and do I need extra components?

The valve insulation heater includes the silicone jacket with mineral wool insulation and integrated lacing anchor wire for fastening; no additional parts are required for standard installation.

Which FPV1812 size fits my piping?

Select the 18 in by 12 in cover when your tee or wye fitting has a circumference between 7 in and 13 in, matching the 3 in thickness and 120V operating voltage.
