Atco Plastic Cement Keeper
These plastic dispensers have a metal cap that includes a polyvinyl-coated paper seal. The brass & aluminum fitting on the cap has a neoprene seal through which the aluminum handle passes. Hand-tighten the fitting to make an air-tight seal, or loosen to adjust the height of the brush in the jar. The washer on top of and inside the cap provide long-lasting strength to the cap assembly. The handle is knurled on one end and threaded on the other end to accept the replaceable horsehair brush. HDPE is compatible with many adhesives, liquids, & oils. Caps are 63mm in diameter.
