JB-19/20 Bellows Type Expansion/Contraction Pipe Fittings

JB-19/20 Bellows Type Expansion/Contraction Pipe Fittings

An expansion pipe fitting with an external-pressure double layered seal (seal-seal structure) that lowers the risk of external leakages.

[Features]
• Large expansion and contraction levels.
• Even in the unlikely event of damage to the bellows, the sealed gland section allows for a quick fix.
• Absorbs expansion and contractions in the axial direction of the pipe caused by temperature changes.
