Screw-Type Non-Locking Filler Caps

Two models of moulded cap with internal screw-thread, designed for 60 mm-diameter necks with matching thread.

The smaller cap has castellated ridges for good grip, and ‘diesel’ embossed on the top surface. It can be supplied fully sealed, or valved and vented. Normal finish is semi-gloss black, with colours on request. A chain is optional. The larger cap will fit the same neck but has a ratchet-ring to prevent overtightening, and a central finger-bar. It is fully sealed, with black fine-textured finish.
