Ultratech, Inc. 482 Lockable Drum Funnel Yellow 23 5/8 in

Ultratech 482 Lockable Drum Funnel for 55-Gallon

The Ultratech 482 is a polyethylene drum funnel designed to fit closed-head and open-head 55-gallon drums. Its lockable yellow lid secures contents while preventing unauthorised access during fluid transfer. The funnel threads onto a 3/4-inch NPT bung hole for a stable connection. This unit suits workshops handling oil or other contaminated liquids.

Practical Limits of the 3/4-Inch NPT Bung Interface

The funnel requires a 3/4-inch NPT threaded opening, so it will not fit drums with different bung sizes or non-threaded heads. A flame arrestor is not included, limiting use where fire codes mandate vapour protection. The fixed 23 5/8-inch outside diameter may not suit drums with narrower chimes or restricted head clearance. Polyethylene construction resists many chemicals but is not rated for all solvents.

Replacing Open Pouring or Unsecured Funnels

This lockable funnel replaces open pouring methods that risk spills, contamination, and unauthorised tampering. The upgrade is worth it when handling regulated liquids that require secured storage between transfers. It also replaces basic funnels lacking a lockable lid, adding compliance support for controlled substances. Buyers needing an integrated flame arrestor or a different bung size should seek alternative models.
