Notice: Due to damage caused by Hurricane Harvey to the petrochemical facilities in Texas, plastic pipe prices are extremely volatile and availability may become an issue. Prices shown on our site are for our current stock and subject to change. We reserve the right to limit quantities or cancel orders. This effects all types of plastic pipe and tubing.
Compression fittings are used primarily for water on copper, vinyl or poly (plastic) tubing. They may be used for oil, but we recommend flare fittings instead.
Unless labeled "lead-free," these fittings may not be used in potable water systems.
Do NOT use these compression fittings for lines carrying pressurized gases.
Compression threads are a very different pitch from iron pipe size threads (or national pipe thread taper). Use a male or female adapter to transition between them. All compression fittings are listed by OD [outside diameter]. See chart for OD to ID comparison.
