PrimeLock® Fittings
A premium PFA fitting for high-purity and corrosive chemical applications
Entegris has supplied innovative connection technology into the high purity chemical handling markets for over 30 years. Our latest innovation, PrimeLock® fittings are simple, robust and very easy to assemble. With audible and visual indicators, users can quickly verify proper makeup of the connection.
The ultra clean design provides enhanced reliability within your system with an all PFA wetted construction. PrimeLock fittings are fully tested using Entegris' stringent testing and qualification methodology. This extremely robust, clean fitting is the most reliable connection technology on the market.
● Easy to assemble, enabling consistent and repeatable fitting makeup
● All wetted components are PFA with broad chemical compatibility
● Robust thread design with no cross-threading, quick makeup and increased sealing force
● Non wetted insert reduces entrapment, leak points and flow interruptions
● No heat required to flare tubing, saving time and money
● Connection verification ring has audible and visual indication of proper fitting makeup
● All fitting sizes are compatible with high-temperature chemical processes.
Applications
● High-purity, corrosive chemical handling
● Semiconductor applications
- Photolithography
- Bulk chemical delivery
- CMP
- Wet etch and clean
- High-temperature cleaning processes
● Solar, LED, flat panel display
● Excellent performance with low surface tension chemistries
