Frequently asked questions
When should I choose BZ external hex plugs over APB internal hex plugs?
Choose BZ external hex plugs when outer installation space is open and you want convenient installation or removal using standard open-end or socket spanners.
Is thread sealant pre-applied on BZ plugs?
Factory shipments can include pre-coated PTFE thread sealant or be supplied clean for food/oxygen-compatible thread compound application upon request.
Are larger sizes like 3/4" or 1" available?
Yes. Sizes up to 1" are available in both standard brass and stainless steel. Include large-bore thread requirements in your quotation request.
