The Casing Pipe and Carrier pipe is Wrapped around by Neoprene rubber end seal then compressing the adhesive applied strips edge. Two SS 304 heavy duty worm strap is fastened to fit tightly.
Pipe sizes from 2″ to 42″ are available for a horizontal or vertical application.

IMPORTANT FEATURES AND BENEFITS
- Casing End Seal is used for watertight sealing the annular space between casing pipe and carrier pipe at casing ends.
- Protects against insulation damage or leakage from moisture, water and contaminants.
- It is resistant to heat, cold, vibration, impact, abrasion, corrosive fluids, disbanding, organic and bio-deterioration.
- End seal are designed to address both angular and concentric misalignment of casing pipe without losing the sealing efficiency.
- Wrapped End seal are used for Custom as well as all Standard Pipe Size combination.
- Moulded type End seal are used for a combination of a very large casing pipe to smaller carrier pipes. Seals stretch 7% for size fitting.
- Moulded type End seal allow large thermal expansion and contraction movement most of the flex boot is contained inside the casing pipe. Several arc folds allow pipe to casing movement as required for the application.
