Fittings & Nipples

Fittings and Nipples are vital connecting components for any residential, commercial or industrial piping system because they connect, extend, redirect, and adapt pipe or tube to ensure safe, leak-free, and efficient transport of all types of fluids and gases. Cooney Brothers offers a wide range of pipe fittings and pipe nipples from trusted manufacturers like Gruvlok and Cello. We stock fittings and nipples in various configurations, connector types and materials—including popular products like press fittings, grooved fittings, pipe nipple sets, and much more—to support numerous industries with strengths and versatility.

Data centers need high-reliability fittings to maintain chilled water, coolant, and refrigerant loops in data center cooling systems, but they are particularly important during installation and system maintenance. Fabrication shops rely on high-quality fittings and nipples every day as essential building blocks for assembling piping spools, skids, and custom systems. Water and wastewater treatment plants require corrosion-resistant, pressure-rated fittings to maintain chemical dosing lines, filtration systems, and distribution networks that keep treatment operations stable and compliant.
