Pall PD2 Powder Bag Cup End Cap 2 in. HDPE Lot of 20 End Caps

Pall Biotech Allegro PD2 Single-Use Powder Bag Cup End Cap, 2 in. Sanitary Tri-Clamp, High-Density Polyethylene (4101083S) – Pack of 20 End Caps

The Pall Biotech Allegro PD2 2-Inch Powder Bag Cup End Cap (4101083S) is a precision-molded protective closure designed to seal and safeguard sanitary 2-inch Tri-Clamp connections on single-use powder handling bags, port assemblies, and bioprocess transfer lines. Constructed from high-purity, medical-grade High-Density Polyethylene (HDPE), this end cap provides a rigid, dust-tight physical barrier that prevents physical damage, particulate contamination, and atmospheric moisture ingress during storage, transit, and staging. Engineered to fit standard 2-inch sanitary ferrule and Tri-Clamp profiles, the cup end cap ensures secure, snap-fit or clamp-retained seating without compromising ferrule face integrity. Supplied as a lot of 20 individual end caps, this component is cleanroom-manufactured and fully compliant with biological reactivity and cleanroom processing standards for biopharmaceutical manufacturing.

Technical Performance & Structural Attributes

• High-Purity HDPE Construction: Molded from pharmaceutical-grade high-density polyethylene resin exhibiting high impact resistance, chemical inertness, and low extractables.
• Precision 2-Inch Tri-Clamp Fit: Custom-contoured cup profile aligns perfectly over standard 2-inch sanitary ferrules to shield critical sealing faces from scratching or abrasion.
• Contamination-Free Protective Barrier: Prevents dust accumulation, particulate settling, and environmental moisture intrusion on single-use powder bag outlets prior to process coupling.
• Smooth Cleanroom Design: Non-sloughing, smooth external finish eliminates particulate generation and simplifies wipe-down sanitization with isopropyl alcohol or sporicidal agents.
• Gamma Irradiation & Sterilization Compatible: Formulated to withstand standard bioprocess gamma sterilization dosing without material degradation or discoloration.
