Pall PD2 Powder Bag Gasket 2 in. Clear Silicone Pack of 10 Gaskets

Pall Biotech Clear Silicone Powder Bag Gasket, 2 in. Tri-Clamp Profile (4100142CS / PD2) – Pack of 10 Gaskets

The Pall Biotech 2-Inch Clear Silicone Powder Bag Gasket (4100142CS / PD2) is a precision-molded, hygienic sealing component engineered for single-use bioprocess powder containment, material transfer, and solid-liquid addition systems. Designed specifically for integration with Pall Allegro powder bag assemblies, stainless steel charge bottles, and sanitary 2-inch Tri-Clamp flange connections, this gasket forms a leak-tight, dust-free seal during critical solid ingredient additions. Molded from high-purity, platinum-cured clear silicone, the gasket exhibits superior flexibility, low compression set, and complete biological inertness. The high transparency of the clear silicone formulation allows operators to visually verify seal seating, flange alignment, and sanitary cleanliness. Supplied as a pack of 10 gaskets, this product meets stringent USP Class VI and ISO 10993 biopharmaceutical compliance standards, ensuring minimal extractables and non-pyrogenic fluid and powder isolation.

Technical Performance & Structural Attributes

• Platinum-Cured High-Purity Silicone: Formulated with pharmaceutical-grade silicone to minimize organic extractables, leachables, and total organic carbon (TOC) shedding into process streams.
• Sanitary 2-Inch Tri-Clamp Flange Profile: Precision-molded geometry aligns perfectly with standard 2-inch TC ferrule faces to prevent gasket intrusion into the powder flow path.
• Visual Seal Verification: Fully clear, transparent material allows immediate visual inspection of gasket seating, mechanical compression, and freedom from powder bridging.
• Low Compression Set Resistance: Maintains elastic seal integrity under continuous mechanical clamp pressure and varying process temperature gradients.
• Bioprocess Chemical & Thermal Stability: Resists degradation from mild acids, bases, alcohol-based sanitizers, and high-temperature autoclave cycles.
