Can you supply small quantities of materials for research and development purposes?

Yes, we offer both bulk and small quantities of sputtering targets, evaporation materials, and spherical powders to support research, prototyping, and development projects.

Silicone Rubber (Si) O-Rings (0.040-0.070 Section)

Silicone Rubber (Si) O-Rings (0.040–0.070 Section): Ultra-Compact Sealing for Vacuum, Laboratory, and Instrumentation Systems

Silicone Rubber (Si) O-Rings (0.040–0.070 section) from TFM are precision-engineered for static sealing in miniature ports, valves, and instrumentation assemblies. These O-rings are molded from 1200-70 grade silicone, offering a 70 durometer hardness and characteristic brick red color. Designed for applications where space is limited but thermal stability and chemical compatibility are essential, they maintain consistent sealing across a wide temperature range of –50°C to +230°C.

Ideal for vacuum systems, analytical instruments, and low-pressure gas lines, these small-section silicone O-rings provide reliable performance without compromising material purity.

Key Features:

Material: Silicone Rubber (Grade 1200-70)
Cross-Section Range: 0.040″ – 0.070″
Durometer: 70 Shore A
Color: Brick Red
Temperature Range: –50°C to +230°C

Performance Highlights:

Excellent Resistance to ozone, water vapor, weathering, and dilute acids
Ideal for Static Seals in compact assemblies and vacuum flange connections
Non-Reactive Composition, free of additives or plasticizers—cleanroom compatible
Moderate Bakeout Compatibility, usable in precision heating environments
Stable at Cryogenic Conditions, suitable for refrigerated and thermal cycling applications

Applications:

UHV-compatible static seals for mini KF flanges and test ports
Compact seals in mass spectrometers, pressure gauges, and sensor housings
Analytical gas handling equipment where elastomer reactivity must be minimal
Static gaskets for medical devices, cleanroom utilities, and biotech instruments

TFM’s Silicone Rubber (Si) O-Rings (0.040–0.070 section) combine compact design with premium sealing performance—ideal for demanding lab and industrial applications.
