Lightly oil the cone of the screw sleeve and the thread of the union nut. With sealing cone screw-on fittings with O-ring (AOL / AOS), the pre-stressing of the O-ring must be bridged and the sealing cone must lie metallically flush against the cone of the HL/HS connector. At this point, the cutting ring may be allowed to rotate, but must not move axially. Tightening torques for stainless steel fittings and for fittings with UN/UNF threads available upon request. The entire fitting consists of the threaded connector, the spacer ring with O-ring seal, the pressure ring and the union nut.
If the 3 sides of T-fitting are similar in size then it is called as Equal tee otherwise it is called as Unequal tee. The advantages of this method are durability, speed, neatness, and safety. Some crimped fittings are designed to be used with copper tubing, without requiring flux or filler metal. Although crimped fittings are suitable for drinking-water pipes and other hot-and-cold systems , they are substantially more expensive than sweated fittings. Where many connections must be made in a short period of time , soldering is quicker and less expensive joinery than compression or flare fittings.
They are used to allow an auger (or plumber’s snake) to clean out a plugged drain. Since clean-out augers are limited in length, clean-outs should be placed in accessible locations at regular intervals throughout a drainage system . They are also known as “rodding eyes”, because of the eye-shaped cover plates often used on external versions. These compression connections on water shutoff valves under a kitchen sink show evidence of slow seepage .
Install the valve following the established solvent procedure. A suitable support should be placed under the valve body to hold the weight of the valve. Be sure to adhere to proper curing times, and wipe off any excess cement that might have accumulated at the joint bead. The pressure losses and ow resistance in a line system are dependent on the internal diameter of the pipe, the ow velocity and the properties of the hydraulic oil .
Major pressing of fittings to pipes or other fittings is performed using electrically powered press equipment, but mechanically driven press equipment is also available. Most of the major brands further have a plastic slip on the end of the press fittings allowing a simple identification if a press fitting has securely been installed. Further, the installation does not use any welding; press fittings with appropriate and region specific certification may be installed for gas lines.
To an uneducated homeowner, pipe fittings are as numerous and confusing as choosing the right screw or nail for a construction project. The materials vary and the specific purpose, although precise, seems daunting to figure out. Our plumbers in Houston & Rosenberg can help repair or repipe your yard. We can help repair and repipe gas lines and water lines, whatever you need, our plumbers can help!

Oil the thread of the union nut, the cutting ring and the screw sleeve thread. In these threaded connections, the cutting ring has been pre-assembled by the manufacturer. The sealing cone is fitted with an O-ring and is shaped so as to fit precisely inside the mating part of the threaded connector. Although flare connections are labor-intensive, they are durable and reliable. Considered more secure against leaks and sudden failure, they are used in hydraulic brake systems, and in other high-pressure, high-reliability applications. Properly welded joints are considered reliable and durable.
In Concentric reducer which is also known as a conical reducer, the center of both the ends is on the same axis. When the center lines of the larger pipe and smaller pipe are to be maintained the same, then concentric reducers are used.
They can be tted either into the screwed joint or into specially made devices. In either case the cutting ring and its edges are moved axially as the union nut is tightened. 900#, 1500#, and 2500# stainless steel flanges are available. Call or email us for those or any custom stainless steel flanges. 18″, 24″, 36″, and 48″ lengths are stocked in addition to the standard stainless steel nipples.
A closet flange is a specialized flange designed to be flush with the floor, allowing a toilet to be installed above it. The flange must be mechanically strong to accommodate slight misalignments or movements, and resist corrosion. Caps, usually liquid- or gas-tight, cover the otherwise open end of a pipe. The exterior of an industrial cap may be round, square, rectangular, U- or I-shaped, or may have a handgrip.
