Septum injector nuts are a simple way to provide syringe access to any point of a gas or liquid system. This injector nut includes a Valcon T polyimide septum support that accepts a standard 1/4" GC septum. The nut's 1/8" external fitting detail can connect directly to common external type fittings, or can be adapted to Valco-style internal fittings using an external/internal union or reducing union.
