Glove Ring/Cuff: Temperature Range -20°C to +120°C

Component Specifications

Definition

A glove ring or cuff is a critical containment component in glove port assemblies used in industrial isolation systems. It serves as the mechanical interface that securely attaches disposable or reusable gloves to glove ports on isolation chambers, glove boxes, or biosafety cabinets. This component ensures an airtight seal while allowing operator hand access for manipulation inside controlled environments. It typically consists of a rigid annular frame with attachment mechanisms (clamps, bolts, or quick-release systems) and sealing surfaces (gaskets or O-rings) to prevent contamination leakage.

Working Principle

The glove ring/cuff operates on mechanical sealing principles. It creates a compression seal between the glove flange and the port opening using clamping force, which compresses gasket materials to form an airtight barrier. This prevents particulate or gaseous exchange between the isolated environment and external areas while maintaining glove flexibility for manual operations. Quick-release mechanisms allow for rapid glove changes without compromising containment integrity.

Materials

Stainless steel (304 or 316 grade), aluminum alloys, or engineered plastics (polycarbonate, PTFE). Sealing elements: silicone, EPDM, or Viton gaskets/O-rings. Surface finishes: electropolished or powder-coated for corrosion resistance.

What is the primary function of a glove ring/cuff?

To create an airtight seal between gloves and isolation chamber ports while allowing manual access to controlled environments.

How often should glove rings/cuffs be inspected?

Visual inspection before each use, with formal integrity testing every 6-12 months depending on application severity.

Can glove rings be used with different glove materials?

Yes, but compatibility must be verified for chemical resistance and sealing performance with specific glove materials.
