When working with HPLC or chromatography systems, the small but essential ferrule can be the key to a secure connection. The 2.5mm and 3.0mm PEEK Ferrules are specifically designed to firmly hold capillary tubing within a compatible fitting, making the selection based on size straightforward. Simply match the outer diameter of your capillary tube with the corresponding ferrule size: use a 2.5mm ferrule for a 2.5mm tube, and a 3.0mm ferrule for a 3.0mm tube.
| Model | Material | Top OD | Overall Height | Height |
|---|---|---|---|---|
| YXRH-251 | PEEK | 2.5mm | 4.5mm | 3.2mm |
| YXRH-30 | PEEK | 3.0mm | 5.0mm | 4.50mm |
| YXRH-301 | PEEK | 3.0mm | 4.8mm | 3.20mm |
For installation, first insert the capillary through the ferrule into the fitting. Tightening the fitting will allow the ferrule to grip the tubing securely, preventing movement. This ensures precise positioning during connection or disconnection processes. A common error is selecting a ferrule based solely on fitting size without considering the actual capillary diameter, so verifying the internal tubing measurement beforehand is advisable.
PEEK material offers significant advantages as it is lightweight, chemically resistant, and well-suited for various laboratory fluid applications. These ferrules can be used across HPLC fittings, chromatography systems, and other related fluidic assemblies. When replacing an existing ferrule, it is usually best to match the new one to your capillary’s outer diameter and fitting setup. If in doubt, you can send us the capillary diameter along with a photo or description of the fitting for assistance.
Looking for a PEEK Ferrule factory for your capillary tubing? Reach out with your capillary outer diameter, fitting type, or specific requirements. We can provide product specifications, samples, OEM support, and bulk supply, and help verify the correct ferrule before you place an order. If you have an existing ferrule or fitting, simply send us its specifications or a photo, and our team can help identify the appropriate replacement.
