Priced conservatively, these caps for GL38 and GL45 glass bottles
have 1/4-28 threaded ports in a PTFE insert, with expanded PTFE
gaskets. Each port has a through-hole for 1/8” OD tubing; push tub-
ing through the cap to supply your system. All ports are machined at a
10 degree angle to simplify threading of tube connections.

THREADED CAPS FOR
NALGENE 38 - 430 BOTTLES
Although similar to a standard GL38 thread, Nalgene 38-430 bottles
require a slightly different bottle cap design for a proper seal. Caps
include PTFE insert and gasket with Polypropylene collar and angled
1/4-28 ports.
