Product Description
Close off the bottom arm while vacuum or gas keeps flowing through the side arms: this T-configuration valve body makes that possible in a compact, low hold-up design. It is a practical choice for drain points and sampling ports on manifolds.
This listing is for Kimble catalog number 826422-0004: HI-VAC Low Hold-Up Valve for PTFE Plugs with Extended Tip, Size 4, valve only. The borosilicate glass 3.3 body is supplied without a plug and accepts extended-tip PTFE plugs of the same size. The design avoids tip O-ring exposure, the primary seal is an FKM O-ring on a tapered seat, and the precision thread allows bleed use up to half a turn. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
