Barndoor Ag Dura Products DP-C4003B-E 6 in. Double Bung Lid with 2 in. Manual Buttress Vent, EPDM Gasket | DEF Tank Accessory

Heavy-duty double-bung lid and manual vent built for DEF tanks and applicator tanks. The unit uses an EPDM gasket that acts as a breather vent and offers strong resistance to heat, UV exposure, aging and harsh weather, making it suitable for outdoor installations. The buttress manual vent begins venting at any pressure differential to relieve pressure while helping prevent non-flammable liquids from leaking during normal sloshing in transport and handling. The double bung configuration provides two filling/extraction points and includes a standard thread for attaching a drum pump or drum pump tube. Product specifications: Buttress manual vent — 2 in. wide; Lid — 6 in. double bung; Model DP-C4003B-E by Barndoor Ag Dura Products.
