2″ NPT Manual Poly Bung Vent (EPDM)
$3.81
The CNE‑VENT (marketed as a poly automatic vent with 2″ NPT threads) is a simple, rugged tank breather/vent designed to provide proper atmospheric ventilation for above‑ground chemical and liquid storage tanks. It allows air to flow into and out of the tank as fluid levels rise and fall, helping to prevent vacuum formation (which can restrict flow) or pressure buildup (which can stress the tank walls). Proper venting like this helps maintain tank integrity, improves dispensing performance, and reduces the risk of damage due to internal pressure fluctuations.
Application:
Ideal for polyethylene storage tanks where basic breather vents are required — particularly on farm, industrial, or bulk storage tanks to ensure smooth and safe fluid transfer.
