2'' NPS/BSP male IBC vent, anti vacuum & pressure

HMVMN20MM027

2″ NPS / BSP Male IBC Vent – Pressure & Anti-Vacuum

Thread: 2″ BCS G2 × 11.5 (compatible with 2″ BSP / 2″ NPS)
Connection: Male
Function: Pressure relief & vacuum relief
Materials: Glass-filled polypropylene body / polypropylene elastomer seals (G/P/P) / 316 stainless steel spring

Product Description

This 2″ male IBC vent is designed to provide controlled pressure and vacuum relief for Intermediate Bulk Containers (IBCs). It helps protect the container from deformation during filling, decanting, and temperature-related pressure fluctuations.

The vent allows air to enter the IBC during product discharge to prevent vacuum collapse, while also relieving excess internal pressure to maintain container integrity and operational safety.

Applications

• Decanting liquids in 1–20 litre increments
• Preventing IBC panel deformation during discharge
• Releasing internal pressure build-up (3–4 PSI) during storage or transport
• Suitable for a wide range of industrial and chemical applications

Key Benefits

• Dual-function pressure & anti-vacuum design
• Compatible with 2″ BSP and 2″ NPS IBC outlets
• Robust glass-filled polypropylene construction with excellent chemical resistance
• Simple screw-in installation
• Designed to extend IBC service life and improve operational safety
