End Fitting, PEEK, for 4.6 mm ID columns, ARE-Applied Research brand. 5/PK.
Additional Info:
The 49333‑EF4‑005 PEEK End Fittings are precision-machined column connection components designed for 4.6 mm ID All‑PEEK HPLC column hardware systems. Supplied in a 5/pack configuration, these fittings are ideal for column packing, assembly, and maintenance workflows requiring consistent and reliable performance.
Each end fitting provides a critical interface between HPLC tubing and the column body, featuring:
10‑32 female inlet thread (standard HPLC tubing connection)
1/2‑20 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 metal‑sensitive analytes.
