Model 4300R Insulated Saddle for Cold or Hot Service

Description: 

The Buckaroos Model 4300R insulated saddle is designed primarily for outdoor use on cold and hot service, but can also be used indoors. Meets MSS SP-58, 9.2.2 for Type 40 Shields.

Features / Benefits:

  • A complete composite assembly, for Fast and Easy Installation.
  • A 360-degree section of polyisocyanurate pipe insulation for greater Thermal Efficiency and compressive strength. With a 4.0 PCF bottom support-section and a 3.0 PCF top section.
  • A 6 mil thickness, .01 perm rated industrial grade vapor retarder film for Superior Condensation Control.
  • A G-90 galvanized steel Buckaroo 360-degree self-clamping shield for Maximum Insulation Protection at hanger locations.
  • A lock-joint to Reduce Heat Gain/Loss along the longitudinal seams to Save Energy.*
  • Furnished with Branded Binder Straps for Guaranteed Top-Shield Security.

The Model 4300R (Recessed Insulation) has the insulation recessed inside the saddle for a vapor-barrier mastic seal at the butt joint. Always install the specified insulation thickness to insure system performance.

4300R (Recessed) Insulated Saddle

Saves Energy! Saves Labor! Saves Money! 

*Lock Joint feature not available on all sizes.

Intended Application:

For outdoor use on refrigeration lines, chilled water lines, cold-process piping and thermal-cyclic systems. Use on cold systems where control of condensation is a critical requirement. Use on hot systems up to 300 degrees F to standardize saddle specification. Ideal for domestic hot water and low-pressure (50# max. pressure) steam lines. The Model 4300R insulated saddle saves energy. Insure complete system integrity by eliminating compromised thermal performance at all hanger and support locations. Due to its complete design, the Model 4300R insulated saddle saves labor because it can be installed rapidly by any qualified contractor. The Model 4300R insulated saddle is always a wise investment!
