3/8" Gum Rubber Tubing for Vacuum Applications

Premium pure gum rubber tubing engineered for demanding vacuum system applications. This formulation resists collapse under vacuum conditions, delivering superior performance compared to standard soft or low-durometer alternatives. Ideal for mechanical vacuum pumps, laboratory equipment, and industrial processes requiring reliable fluid transfer.

Key Performance Features:

• Vacuum-rated construction with 29 in. Hg maximum rating
• Tear and puncture resistant material
• Maintains shape integrity and memory after extended use
• Broad chemical compatibility with acids, solvents, and gases
• Extended temperature stability from -70°F to 180°F
• Exceptional flexibility for simplified routing and installation
• Barbed fitting compatibility for secure connections
