PTFE adapters provide an easy and vacuum tight connection from a standard tapered glass joint to KF, QF, or NW flanges
The viton oring seals great after repeated uses and only needs periodic replacement for the part to last indefinitely. PTFE is chemical resistant to almost all materials and will not breakdown or degrade. The design and dimensions are engineered to provide the largest hole opening and while maintaining rigidity. Our unique design is a shorter overall length which increases the allowable hole diameter and reduces material and cost. Also compatible for use with medium/short joint options. These adapters are made in house and avilable with short lead times. Female end connects to a male (inner) glass joint.
