Key Features
- High-grade Nitrile (Buna-N) dynamic Ultra-Flex (UF) membrane optimized specifically for petroleum oil transfer lines.
- Ultra-Flex flexible engineering provides a highly responsive contour to maximize self-priming suction vacuum lift paths.
- Exceptional resistance to dynamic chemical swelling, softening, and blistering when exposed to raw fuels and grease.
- Retains superior material elasticity, compliance, and structural memory at lower factory floor operational temperatures.
- Precision molded perimeter thickness creates a drop-tight static perimeter seal lock against liquid fluid caps under torque.
