Questions about this item

Should I pick the 18 in by 6 in jacket or a different size for my valve?

Choose this jacket when your valve circumference falls between 7 in and 13 in; the 18 in length and 6 in width with 3 in thickness are fixed for this model.

What does the 900 degree rating mean once the jacket is on a live pipe?

The silicone-coated fiberglass cloth facing and fiberglass mineral wool insulation are rated for continuous ambient temperatures up to 900 °F, so the cover will not degrade at typical steam or hot-water service temperatures.

How does the quick-release flap and wiretwist fastening work with the R-value of .48?

The fabric flap and wiretwists let you wrap and secure the jacket without tools, while the 3 in thick insulation delivers an R-value of .48 to reduce heat loss and meet OSHA surface-temperature guidelines.
