Pureloc® PFA Compression Fittings
Features
- PFA body made from virgin, high purity materials
- Ideally suited for corrosive environments and chemical applications
- Less surface particulate resulting in cleaner operation
- Easy to disconnect and reuse
- Excellent lock and seal ability
- Numerous configurations available
Notes
With a fitting body made from virgin, high purity PFA fluoropolymer, PURELOC is ideal for ultra-pure fluid applications where contamination-free systems are used. This includes semiconductor manufacturing, food and beverage processing, medical and biomedical, laboratory, chromatography equipment, and the chemical industries.
The gripper coupled with the precision-made ferrule provides excellent leak-tight connections and prevents tubing blow-out.
Materials of Construction:
Wetted: PFA body, PTFE ferrule
Non-wetted: PFA nut, titanate filled ETFE gripper
Pressure Ranges:
125 PSIG (8.6 bar)
Assembly Instructions
Cut tubing (A) cleanly at 90°.
Push tubing through small end of nut (B), gripper (C), ferrule (D), and seat the tubing end into the fitting body as far as it will go (E).
Thread the nut onto the body and finger tighten while assuring that tubing remains seated in bottom of fitting. To complete the installation, tighten nut with a wrench at least one additional turn. Avoid overtightening.
Size Recommendations
See chart; these sizes represent the only fluoropolymer tubing dimensions recommended for use with Pureloc fittings.
The values above are typical for the material used in manufacture, except where noted, and are meant only as a guide to aid in design. Field testing should be performed to find the actual values for your application.
| FITTING SIZE | RECOMMENDED TUBING SIZE |
|---|---|
| 1/8” | 1/8” O.D. x 1/16” I.D. |
| 1/4” | 1/4” O.D. x 5/32” I.D. |
| 3/8” | 3/8” O.D. x 1/4” I.D. |
| 1/2” | 1/2” O.D. x 3/8” I.D. |
| 3/4” | 3/4” O.D. x 5/8” I.D. |
