Product Description
PTFE plugs turn smoothly without grease, so they will not contaminate samples or freeze in the barrel the way glass plugs can. These straight bore plugs are a simple way to upgrade or repair burets, funnels and other stopcock glassware.
This listing is for Kimble catalog number 821001-0004: PTFE Plug, with straight bore 4 mm, 1 per case. Plugs are made from chemically resistant, self-lubricating PTFE with a 1:5 taper and straight bores of 2, 4 or 6 mm. A high-temperature PTFE version is available in the 2 mm size. Choose single plugs or cases of 12, and confirm the plug size and O-ring size against your barrel. Order it from LIGHT LABS and keep your lab stocked with genuine DWK Life Sciences products.
