End Fitting, PEEK, for 7.5 mm ID columns, ARE-Applied Research brand. 10/PK.
Additional Info:
The 49333‑EF7‑010 PEEK End Fittings are precision-machined column connection components designed for 7.5 mm ID All‑PEEK HPLC column hardware systems. Supplied in a 10/pack configuration, these fittings are ideal for high-throughput semi‑preparative column packing, system builds, and routine maintenance workflows.
Each end fitting provides a critical interface between HPLC tubing and the column body, featuring:
10‑32 female inlet thread (standard HPLC tubing connection)
5/8‑18 column thread (column tube connection)
Manufactured from high-performance PEEK (polyether ether ketone), these fittings ensure a fully bioinert, metal‑free flow path, making them ideal for proteins, peptides, nucleic acids, ions, and other metal‑sensitive analytes.
✅ Key Benefits
