Ace Glass 7632-01 2-Port (GL14) Polypropylene Cap

The heart of the GL45 connection system is a GL45 polypropylene cap with 2 GL18 threaded ports. Modular accessories include polypropylene tube connection caps, GL18 solid polybutylene terepthalate (PBT) caps, GL18 PBT pressure equalization caps and PTFE cap inserts to accommodate various sizes of tubing. A typical application is the safe transfer of liquid media within a closed and sterile system for which you'd need (1) two-pack GL45 cap, (2) -07 equalization caps, and some combination of solid caps and tubing connections with inserts.
