A telescopic fitting that allows for longitudinal adjustment. Essential for installing or removing valves and pumps. The example shown is for a 100mm pipe.
Body Material: Ductile Iron (DI), as explicitly marked on several units. This material is chosen for its high tensile strength and ability to withstand high pressure without being brittle.
Standardization: All products are manufactured to IS:9523. This is the Indian Standard for “Ductile iron fittings for pressure pipes for water, gas, and sewage”.
Quality Marks: Many units feature the ISI mark and CM/L numbers, indicating third-party quality certification for the Indian market.
Coating: The black finish is typically a Bitumen Black Paint or an Epoxy Powder Coating designed to prevent corrosion from soil and water contact.
Fasteners (Dismantling Joint): The long bolts (tie-rods) are typically made of Galvanized Steel to prevent rusting.
