Full vacuum rated silicone hose with steel wire or heavy braid reinforcement. 0 bar absolute. No collapse. Pharma, food, and lab vacuum applications. Custom sizes.

FDA 21 CFR 177.2600 USP Class VI REACH RoHS

Product Overview

Standard silicone tubing collapses under vacuum, restricting flow and potentially damaging equipment. Rekky Technology’s Vacuum Rated Silicone Hose is specifically engineered to maintain its full circular cross-section under deep vacuum conditions down to 0 bar absolute (full vacuum, -1 bar gauge).

We achieve full vacuum capability through two reinforcement strategies: (1) a 316L stainless steel wire helix embedded in the hose wall that acts as a rigid skeleton, or (2) a heavy multi-ply textile or fabric reinforcement that resists the inward crushing force. Both constructions maintain the purity and flexibility of platinum-cured silicone while eliminating the vacuum collapse risk.

This hose is essential for pharmaceutical vacuum filtration, food vacuum packaging, laboratory vacuum ovens, biotech centrifuge connections, and any process where the hose must handle both suction and discharge without changing shape. The smooth inner bore ensures unrestricted flow even at high vacuum levels, and the platinum-cured inner surface prevents particle shedding that could contaminate sensitive products.
