4" Flexible Rubber Cap
This 4 inch flexible rubber cap is engineered for sealing and protecting pipe ends in soil, waste and drainage systems. It combines a 300 series stainless steel frame with EPDM or Neoprene rubber to deliver corrosion resistance and weatherability in demanding plumbing environments. The cap is designed for no-hub cast iron pipe installations, providing a secure, flexible seal suitable for both commercial and residential applications.
The rubber compound meets typical industry standards for elasticity and durability, ensuring a long service life in variable temperatures. Stainless steel 300 series is a standard choice for such fittings due to its resistance to rust and chemical exposure. This cap is packed at 50 pieces per carton, with Xingang, China, as the port of loading, making it practical for bulk import by distributors and contractors.
Common applications include capping drain pipes, vent stacks and sewer lines to prevent debris ingress and water leakage. The flexible design accommodates minor misalignments in pipe ends, reducing installation time. Buyers typically source these caps in bulk for plumbing projects, with packaging suitable for containerised shipment. Confirm compatibility with your pipe material and diameter before ordering.

Sourcing 4" Flexible Rubber Cap from Richang Qiaoshan Trade Co. Ltd. - China Import Guide
Before ordering, verify the cap’s compatibility with your pipe material and diameter. Confirm whether EPDM or Neoprene rubber is used, as each has different chemical resistance properties. Request samples if your project requires testing for fit or performance in specific conditions.
Logistics details to confirm include the port of loading (Xingang, China), packaging (50 pieces per carton) and whether the supplier can accommodate custom packaging for bulk orders. Discuss Incoterms such as FOB or CIF, as well as payment terms like TT or LC, to align with your import process.
For quality checks, inspect the rubber for uniformity and the stainless steel for surface finish and corrosion resistance. Request a material test report for the rubber and steel if your application demands strict adherence to standards. Documentation such as a packing list, commercial invoice and certificate of origin should accompany the shipment.
