  • Product typeTarps
  • Antimicrobial closed-cell foam resists mould growth
  • UL 94 rated material meets flame spread index 25
  • Withstands temperatures from -297 °F to 220 °F
  • R-value 4.9 reduces thermal loss on piping
  • Plenum rated for safe use in air-handling spaces

Elastomeric Tee Fitting for 2 in Pipe

This pre-formed tee insulation fits copper or iron pipe with a 2 3/8 in outside diameter. It is supplied unslit for a continuous vapour barrier on chilled-water, refrigerant or hot-water lines. The closed-cell Buna-N rubber/PVC foam resists microbial growth and meets UL 94 and a 25 flame-spread index.

R-Value 4.9 at 3/4 in Wall Thickness

The single figure that determines thermal performance is the 4.9 R-value provided by the 3/4 in wall. It maintains that resistance from -297 °F up to 220 °F, so the part suits both cryogenic and high-temperature hydronic systems without additional jacketing.

Push-On Installation Over Clean Pipe

Slide the tee onto the fitting before brazing or press-connecting the joint, then seal the seams with compatible contact adhesive. The unslit design requires planning the fitting sequence in advance; once the joint is made the insulation cannot be wrapped around it.

Questions about this item

What does the R-value of 4.9 mean once the tee fitting is installed on a 2-inch pipe?

An R-value of 4.9 indicates the insulation's thermal resistance, helping to reduce heat loss or gain on the pipe fitting at operating temperatures between -297 and 220 degrees Fahrenheit.

How does the UL 94 standard and flame spread index of 25 affect where this insulation can be used?

The UL 94 rating and a flame spread index of 25 mean the material meets plenum rating requirements, allowing installation in air-handling spaces per building codes.

What are the physical dimensions needed for this tee fitting to fit my pipe?

This tee fitting is designed for a 2-inch pipe size with a 2 3/8-inch outside diameter, featuring a 3/4-inch wall thickness and an unslit installation style.
