Single-clamp cap plug

What is a Single-clamp cap plug?

Shenchi's leak-proof Single-clamp cap plugis a thin-walled stainless steel pipe fitting used to seal the end of a pipe. Its structure consists of a sealed cap at one end and a single-press connection at the other: the pipe is inserted into the socket to the marked depth, and a special pressing tool is used to perform a single radial compression, causing the fitting and pipe to undergo 360° circumferential plastic deformation and tighten. Simultaneously, the built-in EPDM sealing ring is compressed to achieve an elastic seal, ensuring no leakage at the end.

Custom Marking Service

Shenchi supports marking customers' own brand logos on single-clamp pipe caps with good sealing properties. Laser marking technology is used, ensuring clear and durable logos without damaging the passivation layer on the pipe surface. Minimum order quantity varies depending on specifications, but custom marking can generally be arranged for orders of 1000 pieces or more. Marking location can be selected on the end face or side of the cap; font, size, and pattern can all be designed according to customer requirements.

Main Application Industries

Shenchi's affordable single-clamp pipe caps and plugs are widely used in multiple industries. Building Water Supply and Drainage: End sealing and pressure testing of hot and cold water pipes in residential and commercial buildings. Gas Engineering: End sealing of natural gas and liquefied petroleum gas pipelines and temporary sealing of reserved interfaces. HVAC: End sealing and system pressure testing of chilled water, cooling water, and heating pipes. Industrial Fluids: End sealing of compressed air, chemical liquids, and oil pipelines. Fire Protection Systems: Pressure testing and end sealing of fire sprinkler pipes.

Why are press-fit caps preferred across industries?

Shenchi's high-quality press-fit caps are popular in various industries for three main reasons. First, quick installation: no welding or threading required, a single cap can be installed in 5-10 seconds, significantly shortening the construction period. Second, reliable sealing: the EPDM sealing ring forms a 360° elastic seal after radial compression, ensuring no leakage under PN16 pressure for extended periods. Third, safety and environmental friendliness: cold mechanical connection, no open flame or welding fumes, safe for installation in flammable locations such as gas pipelines and chemical plants. Fourth, easy disassembly: if the seal needs to be opened, it can be loosened with a special tool, unlike welded caps which require cutting.
