BlueLine flexible couplings, expansion joints and bellows are specifically designed to compensate for pipe expansion, vibration and misalignment in process piping and vessels.  All BlueLine flexible couplings, expansion joints and bellows are constructed from uniform-walled isostatically molded PTFE and demonstrate a high level of design consistency throughout the product line.  This consistency-not apparent in competitive products is a result of an optimally designed convolution and a proprietary manufacturing process.

• Diameters from 1" through 12"
• 2,3 and 5 convolutions
• 150 lb ANSI, Class 150 flange drilled and tapped per ANSI B16.5
• Full vacuum and pressure capability
• Face to face dimension standard to most other manufacturers

BlueLine flexible couplings, expansion joints and bellows offer a wide variety of benefits for maintenance and repair personnel including:

• Reliable protection for fragile FRP, carbon or glass equipment and nozzles
• Superior corrosion resistance in acidic and caustic environments
• Heavy walls made from isostatically molded virgin PTFE
• Low spring rates with short face-to-face dimensions
