55/50 Female Ground Glass Joint

SKU:

IND-5550F

Description:

The 55/50 Female Ground Glass Joint is a precision-ground glass connector used to create a removable, airtight glass-to-glass seal between compatible joint sizes. The female side is the receiving taper, ground to match a 55/50 male joint so the two pieces seat securely and consistently. In lampworking and scientific glass work, ground joints are used when you need a dependable connection that can be assembled and disassembled for cleaning, swapping components, or building modular systems such as condensers, adapters, and custom assemblies.

How it is used:

• Pair it with a matching 55/50 male ground glass joint and seat the tapers together with a gentle twisting motion.
• Use it to build modular glass assemblies where parts need to be removed for cleaning, transport, or reconfiguration.
• Keep the ground surfaces clean and protected from grit to maintain a good seal and prevent sticking or galling.
