Quick Navigation:

1. Executive Summary: Instant Sealing for Unused Spigots & Ports

The SOSHH PU10 Transparent Snap-in Blanking Cap is an essential component for bulk material handling systems. Designed as a drop-in replacement for standard snap-in end caps, it provides a 100% dust-tight and airtight seal for unused pipework branches, clean-out ports, and inspection windows.

2. Core Engineering Advantages (Operator-Friendly Design)

  • Integrated Pull Tab: Unlike standard flat caps that are difficult to grip, our ergonomically designed pull tab allows operators to remove the cap in seconds, significantly reducing downtime during maintenance or washdowns.
  • 100% Visual Monitoring: Manufactured from crystal-clear Ether-based TPU, the cap doubles as a highly durable sight glass, allowing operators to safely monitor product flow or blockages without opening the system.
  • Zero-Tool Installation: The internal snap-action band perfectly locks into standard grooved spigots, eliminating the need for hose clamps, tools, or silicone sealants.
  • Sanitary & Food Safe: Fully compliant with FDA 21 CFR 177.2600 and EU 10/2011 regulations for direct food contact.

SOSHH Snap-In Hopper Breather Bags for Dust Relief and Air Venting (FM1 Polyester Felt)

Relieve Hopper Air Displacement While Capturing 99.9% of Sub-Micron Dust Rapid powder batching and gravity filling displace huge volumes of air inside hoppers, bins, and loss-in-weight feeders. When sealed with solid impermeable sleeves, this air displacement causes positive pressure surges that blow out gaskets, aerate powders, and cause erratic weighing errors on load cells. SOSHH Snap-In Breather Bags provide controlled, continuous pressure relief while retaining fine airborne particles down to 1 micron. Constructed from breathable polyester needle felt (FM1) and featuring an integrated snap-in seating band, these bags install tool-free in under 30 seconds directly into standard industry spigots.
