NPS stands for National Standard Straight (in mechanical threads) or more commonly Nominal Pipe Size (in North American industrial pipe sizing standards). When referring to straight mechanical pipe threads (NPSM), unlike tapered NPT threads, the connection relies on a mechanical seal, gasket, or O-ring to prevent fluid leakage under pressure.
Plasson compression fittings are constructed using high-grade engineering thermoplastics. Their bodies and nuts consist of tough polypropylene copolymer enhanced with carbon black for UV stabilization.
In general pipeline and plumbing configurations, the four most common foundational categories of fittings are couplings (used to join two straight pipes together), elbows (designed to change the direction of flow), tees (configured to branch flow off...
No, you do not flare the copper or metal tubing when using a standard compression fitting.
A -6 AN fitting (Army-Navy standard) refers to a specialized high-performance fluid line connector featuring a 3/8-inch nominal tube size (computed as 6 sixteenths of an inch).
In plumbing schematics, product catalogs, and valve specifications, SWT stands for Sweat (sometimes referred to as Solder).
Plasson metric compression fittings are manufactured in a comprehensive range of diameters typically spanning from 16mm up to 125mm or 160mm depending on the specific product line.
No, you typically do not need Teflon (PTFE) tape on the compression joint itself, because the seal is formed entirely by the metal-on-metal or metal-on-pipe compression of the olive against the tubing.
Yes, it is completely acceptable and common to use compression fittings on copper pipes. Compression fittings provide a secure, watertight mechanical seal without requiring open-flame torch soldering or brazing.
Plasson fittings are world-renowned, high-quality mechanical compression fittings designed specifically for joining polyethylene (PE) pipes.
High-Density Polyethylene (HDPE) pipes are typically joined using mechanical compression fittings (for smaller metric or rural diameters up to 160mm), butt fusion welding (melting pipe ends together with heat plates), electrofusion fittings (which fe...
In international piping standards, PN stands for Pressure Nominal (Pressure Rating).
The colored stripes running longitudinally along the exterior of polyethylene (poly) pipes serve as an standardized visual coding system to indicate the pipe's intended application and pressure rating.
In plumbing and pipe fitting terminology, MPT stands for Male Pipe Thread (featuring external threads designed to screw into a matching component), while FPT stands for Female Pipe Thread (featuring internal threads designed to accept a male-threaded...
The most common plumbing and industrial pipe fittings include elbows (used to change flow direction), tees (for splitting or combining fluid streams), couplings (to connect two straight pipes together), reducers (for transitioning between different p...
Plasson is a globally recognized, industry-leading manufacturing brand specializing in high-performance mechanical compression fittings, valves, and piping systems designed primarily for polyethylene (PE) pipes.
Yes, it is entirely possible to overtighten a compression fitting, which can cause severe damage.
FIP stands for Female Iron Pipe (also frequently associated with Female Pipe Thread or FPT).
In North American plumbing standards, CTS stands for Copper Tube Size. It represents a specific sizing convention where the outer diameter (OD) of the pipe is consistently 1/8-inch larger than the nominal size descriptor.
To use a Plasson compression fitting correctly, cut the polyethylene pipe squarely and clean any burrs from the end.
An "olive"—more commonly referred to in North America as a ferrule—is a small, ring-shaped metallic or plastic component used inside compression fittings.
The pressure rating (PSI) a fitting can hold depends entirely on its material composition, size, manufacturing standard, and connection type.
PN-10 (Pressure Nominal 10) is a standardized pressure rating designation indicating that a pipe, valve, or fitting is engineered to safely withstand a maximum working water pressure of 10 bar (approximately 145 PSI or 1 megapascal) at standard ambie...
Professional plumbers typically assemble standard brass compression fittings clean and dry, relying entirely on the mechanical metal-on-metal compression of the ferrule (olive) against the pipe and fitting body to form a watertight seal.
An incoming residential water pressure of 80 PSI is generally considered the maximum safe upper limit for standard household plumbing systems.
In plumbing infrastructure and building drainage schematics, SWR stands for Soil, Waste, and Rainwater.
