About the product
FIX-L is a restrained coupling for steel pipes and stainless pipes, used where pipelines are to be joined, extended or repaired without welding. The coupling is fitted over the pipe ends and tightened with bolts, giving a quick installation. The reinforced anchoring ring provides high axial strength, and stainless steel gripper rings lock against the pipe surface. The seal is available in EPDM for -20 to 100°C or NBR for -20 to 80°C. The coupling tolerates a certain difference in diameter and an angular deviation of up to 4° in smaller sizes and 2° in the largest, and covers outside diameters from approximately 107 to 270 mm. The choice of stainless steel makes it suitable for industry, water supply and infrastructure. Operating temperature: EPDM: -20 - 100°C NBR: -20 - 80°C Angular deflection / side: OD 26-168: 4° OD >206: 2°
Benefits
- Restrained joint that takes up axial forces
- Installed without welding – quick on-site installation
- Stainless steel throughout for long service life
- Tolerates angular deviation and diameter differences for repairs
- EPDM or NBR seal for different media and temperatures
