A Complete Flange Protection System
APS combines three proven technologies into one integrated system designed to eliminate corrosion risks:
Kleerband® Flange
Protectors
Kleergel® Corrosion Inhibiting
Grease
Radolid® Bolt Protection
Caps
Protects the entire flange assembly—face, studs, and gasket.
- Transparent design for 360° visual inspection
- Moisture-proof seal prevents corrosion intrusion
- Built-in grease injection fitting ensures full coverage
- Safety relief vent for pressure control
- Reusable, non-corroding, long service life
Designed for use in harsh environments including refineries, offshore platforms, pipelines, and water systems.
Seals and protects internal components with high-performance synthetic lubrication.
- 100% waterproof and non-toxic
- Maintains performance from -50°F to 375°F+
- Reduces friction, wear, and energy consumption
- NSF H-1 food-grade approved
- Lasts significantly longer than petroleum-based greases
Provides long-lasting protection while extending equipment life.
Protects nuts and bolts from corrosion and environmental damage.
- Easy installation — no tools required
- Snap-on design prevents accidental removal
- UV-resistant, durable materials
- Reusable for long-term use

Keeps fasteners corrosion-free and allows for quick removal during maintenance.
The APS Advantage vs Traditional Methods
- Fully inspectable without removal
- Faster, simpler installation
- Reusable system reduces long-term costs
- Complete protection for flange + bolts + cavity
- Proven corrosion prevention performance
Outdated flange protection methods fall short:
Shrink Sleeves
- Complex installation
- Cannot be inspected without removal
- Time-consuming and costly
Tapes
- Trap moisture inside flange cavity
- Create hidden corrosion
- Non-reusable
Wax & Epoxy Fillers
- Messy and labor-intensive
- Shrink and separate over time
- Difficult to remove
