Our Compression fittings are common among plumbers, contractors, and DIY homeowners because they are simple to install and dismantle. The sleeve grips the tubing and as the nut tightens it. The compression nut forces the ring and pipe against the insert as it closes, producing an absolute seal. Compression fittings include preassembled bodies, nuts, and sleeves for quick installations. Pex Compression Fittings entails inserting the compression insert into the end of the PEX piping, placing the compression ring over the pipework, and tightening the compression nut. Being easy to disassemble works well for plumbers and homeowners who want to modify their own plumbing as they are installed in case disassembly may happen. The fitting is for use with copper, aluminum and Parflex. Such fittings are known for being ready for assembly and disassembly. 61C-03 Dixon Brass Compression Fitting is a Nut, with a 3/16 Tube Size x 3/8-24 Straight Thread. Material to conform to Grade IS 319 Gr.1. Unique feature of Brass Compression Fittings Front and Back Ferrule Chemically treated for Best Biting Performance Nut to be silver plated for Anti-Galling Made from Extruded Bar Stock. Fittings are offered with a BSPP, BSPT or NPT thread. Brass Fittings are manufactured in Heavy and Light Series depending on pressure requirement. They are used to ensure the correct insertion length into the process and provide some degree of resistance to pressure applications. Pex Compression Fittings comprise of a compression insert that goes through the tubing, a compression ring to split off in a diagonal path and a compression nut to form a strong seal. The Effects of Overtightening Compression Tube Fittings Properly sealed tube fitting connections are crucial in a tubing network of any size. Our range of adjustable compression fittings are available in either stainless steel, brass or PTFE. This fitting type is perfect for setups requiring multiple connection points or when disassembly will be needed in the future. When correctly assembled, it creates a tight seal that is void of leaks. Often people wrap PTFE round a compression fitting olive to make sure of a water tight seal.PEX compression fittings are composed of three sections – namely the nut, ring, and insert. Generally a nut will need one whole turn after hand tightening. They can withstand pressures up to 900 psi. Its often said in the trade to not over tighten a compression fitting, leaving you more thread in the case of a leak and not distorting the olive or fitting. Connect these fittings to thick-wall plastic pipe they have thicker, stronger walls than standard-wall fittings, so they can handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation. Hold the compression fitting body tightly with a pair of grips and tighten the nut with a spanner. When the pipe has been cut and cleaned, assemble the compression fitting by sliding on the nut and olive at both ends. Pipeslices are an excellent tool for such a job and are great in tight spaces. This exerts pressure on the olive and bites it onto the pipe.Ĭompression fittings work well if the pipe is clean and cut properly. Using a spanner and a pair of grips the nut is tightened. The two surfaces are the body of the fitting (be it a valve, connector or any other type) and the nut. Compression fittings work by the compression of an ‘olive’ between two tapered surfaces and the pipe itself.
