The SUPCO SSRT3165 is a high-temperature red silicone rubber tubing sold in a 5-foot roll. It features a 3/16 inch inner diameter and is rated for service from -100 degrees F to 500 degrees F, with a working pressure range of 20 to 60 psi. The flexible silicone construction resists heat, moisture, and many common chemicals encountered in HVAC, refrigeration, and related trade applications. Technicians use it for routing low-pressure air, vacuum, or fluid lines in tight service environments where standard rubber or vinyl tubing would fail from thermal stress.
This tubing is suited for residential and light commercial HVAC, refrigeration, and pool or spa equipment where flexible, heat-resistant tubing is required. Typical uses include pressure sensing lines, vacuum lines, condensate routing, and equipment test connections. The bright red color aids identification in multi-line installations. Each roll provides 5 feet of continuous tubing, making it practical for single-service jobs or field repairs without cutting from bulk stock.
Designed as a general-purpose replacement or service tubing for low-pressure air, vacuum, and fluid lines in HVAC, refrigeration, and pool or spa equipment applications.
Installation is typically performed by licensed HVAC technicians, refrigeration mechanics, or pool service professionals. Always relieve system pressure and shut down equipment before disconnecting or replacing tubing. Secure tubing ends fully onto barb fittings and verify there are no kinks or sharp bends that could restrict flow or cause premature wear. Ensure the tubing route keeps it away from surfaces that exceed its rated temperature range.
