Semi-circular NS joint clamps quickly clip into place and can be removed just as easily from working apparatuses. The manufacturing materials have chemical and temperature resistance for uncompromised efficiency even under harsh testing conditions. Choose between conventional metal- and the glassware-friendly plastic styles that will not scratch or damage equipment. The two-tiered NS joint clamps firmly lock ground joint pieces in place for error-free operation, and are offered in color-coded size options.
