Endura-Seals are the CRS alternative to typical silicone-rubber injection port septa for gas chromatography. They work in a 2 part sealing system that includes the septa and the sealing nut.

• Reliably seal against the carrier gas pressure in the inlet
• Capable of being pierced and resealing time after time
• Does not contaminate or bleed material into the chromatographic system
• Resilient to needle wear and tear
• Eliminates coring

The Endura-Seals are available in 11 mm and Shimadzu style kits. Each kit includes 1 sealing nut and 2 septa.
