Ring Sizes: RE-1700 → RE-3500 (1,700mm–3,500mm ID), custom sizes available.
Joint: Vulcanized endless, no visible seam.

Pressure	Saturated Steam Temp	Continuous Rating	Intermittent Rating
1–3 bar	120–144°C	Excellent	Unlimited
3.5–4.0 bar	148–152°C	Good	Up to 100 hrs
4.5–5.0 bar	156–159°C	Fair → Not recommended	Up to 24–50 hrs

Compression vs. Sealing Force:

Pressure Activation Factor: Self-energizing effect increases sealing force up to 4.2× at 4 bar.

Horizontal Sterilizers
- 2,000–3,500mm diameter, 20–30m length
- Operating: 2.5–3.5 bar g, 135–150°C, 80–120 cycles/week
- Recommended Profiles: RUB-L9.5 / RUB-L10.0
- Service life: 12–30 months depending on operating severity
Vertical Sterilizers
- 1,500–2,500mm diameter, top-loading or bottom discharge
- Recommended Profiles: RUB-L8.5 / RUB-L9.5
- Joint Endless Ring preferred
Cage Sterilizers
- High-cycle use (100–150 cycles/week)
- Recommended Profiles: RUB-L9.5 / RUB-L10.0
- Peroxide-cured EPDM for superior compression set resistance

Kernel Plants: Conditioning vessels, driers – RUB-L8.5/9.5
Biogas/Biofuel Plants: Digesters, steam lines – standard EPDM, optional H 係-resistant grade
Industrial Autoclaves: Rubber vulcanization, timber, composites, food – RUB-L8.5/9.5/10.0 depending on size & pressure

Level	Frequency	Activities
Daily	Operator check	Visual steam leaks
Weekly	Technician	Door pressure, seal cleaning
Monthly	Supervisor	Partial inspection, compression set
Quarterly	Engineer	Full inspection, bolts & alignment
Annual	Crew	Complete replacement, groove prep

Stock Recommendations:

RUBASIA EPDM vs Competitors:
- Higher tensile & tear strength, lower compression set
- Superior abrasion and heat-aging retention
- Value rating: +P+P+P+P+P vs competitor 3–4 stars
Environmental Resistance: Excellent to UV, ozone, humidity, and tropical conditions.
