Calpico Pipe Linx (pipe link seals) form a mechanical rubber seal between pipes going through walls, floors, vaults, tanks and pipeline casings. The links make a watertight seal between a pipe and a wall hole. They can also seal the gap between an inner pipe and outer pipe sleeve or pipeline casing. They seal the gap between electrical conduit and the outer conduit, or between electrical conduit and the wall hole it passes through.
| Part number | Description | Application |
|---|---|---|
| CSL | Standard EPDM Pipe Links with zinc plated hardware | Suitable for most applications in water, both above ground and direct burial. Provides electrical insulation where cathodic protection is required. |
| CSL SS | Pipe Links with 304 grade stainless steel hardware | Environments where corrosion-resistant hardware required. EPDM rubber resistant to most inorganic acids and alkalis, some organic chemicals (acetone, alcohol, ketones). |
| CSL SSS | Pipe Links with 316 grade stainless steel hardware | For applications where lower grade Stainless Steel hardware is not suitable and a higher degree of corrosion resistant hardware is required. |
| CSL N | Nitrile Pipe Links for petroleum based applications | Nitrile rubber is suitable for most hydrocarbons, fats, oils, greases, hydraulic fluids, chemicals and solvents — gasoline, jet fuel, water, motor oil, kerosene, methane, etc. |
| CSL N SS | Nitrile Pipe Links with 304 stainless steel hardware | Combination of stainless steel hardware and oil-resistant rubber. |
| CSL N SSS | Nitrile Pipe Links with 316 stainless steel hardware | Combination of higher grade stainless steel hardware and oil resistant rubber where the ultimate corrosion protection is desired. |
| CSL T | High Temperature (consult our sales staff for availability) | Silicone rubber is ideal for temperature extremes. |
The link seals are designed to make a hydrostatic seal of up to 20 psi & 40 ft. of head. In addition to their sealing properties, the links help absorb vibrations and shocks. They also insulate the inner pipe from all the outer structures, including outer pipe sleeves, pipeline casing, walls, and tanks.
The link seals are made from EPDM synthetic rubber with heavy duty plastic pressure plates, which are resistant to sunlight and ozone. Link seals are also available in Nitrile for petroleum based applications. All bolts and nuts are plated with an anti-corrosive zinc coating. Stainless steel bolts and nuts, both 304 & 316 grade, are also available. Twelve different sizes of CSL links are available, which make up most pipe sizes from 1/2″ up to 120″.
Boxed CSL links include Installation Instructions for an easy assembly in a step-by-step manner. Special tools are not required.
