Victaulic is a developer and producer of mechanical pipe joining systems and is the originator of the grooved pipe couplings joining system.[1] Victaulic is a global company with 15 major manufacturing facilities, 28 branches, and over 3600 employees worldwide. Currently, Victaulic headquarters is located in Easton, PA.

The vision of the Victaulic joint emerged in World War I. Its original purpose was designed mainly for military applications but quickly became popular in other niche markets. Since 1919, Victaulic has been producing grooved mechanical couplings and pipe joining systems while expanding its reach across different markets.[1]


Example of Victaulic Piping

Victaulic specializes in the development of couplings, valves, and fitting technologies for a variety of industries. Its main products are:



Grooved coupling pipe joining systems uses a roll grooving technique to join pipes and pipe joining components. A groove is placed on the end of two pipes to prepare the pipes engagement with the coupling housing and gasket. The gasket creates a pressure responsive seal on the outside diameter of the pipe, unlike standard compression joints, where pressure acts to separate the seal. The gasket sealing is enhanced as the coupling housing is tightened onto the pipe end. "The economics of the grooved method derive from simplified assembly that involves three basic concepts: a pressure responsive gasket that creates a leak-tight seal; couplings that hold the pipe together; and fasteners that secure the couplings.[10]

Mechanical piping joining systems are being used in HVAC, plumbing, fire protection and mining, water and waste water treatment, oilfield operations, power plants, military, marine systems and other industrial applications due to the time and labor-saving features associated with installation.[11] Mechanical piping systems offer an alternative to welding, threading, and flanging for joining two pipe ends.

Early history

Victaulic Patent filed on 4 April 1919 by Ernest Tribe.

The vision for joining pipe with bolted mechanical couplings, “Victaulic Pipe Joint” emerged in World War I. Its original purpose was designed mainly for military applications but quickly gained popularity in other commercial and industrial markets. The concept, emerged when inventor Lieutenant Ernest Tribe, of the Royal Engineers, devised a special form of joint for use on pipes and cylinders containing gasses and chemicals under very high pressure. Tribe, in conjunction with Dr Henry Hele-Shaw, a noted English hydraulic engineer, had been engaged by the British Government during the war to advance trench warfare tactics.[12]

Lt Tribe was among the first group of soldiers that were trained to operate a trench warfare weapon called a flamethrower. According to Thomas Wictor, the Author of “Flamethrower Troops of World War I: The Central and Allied Powers,” Lt Tribe accompanied the delivery of Vincent battery flamethrowers to allies in World War I and also trained soldiers in the use of the weapon. In the early phases of utilizing the flamethrower operators were experiencing noxious design problems.The flame tube that transferred oil would come apart, spraying operators with burning oil. The faulty connector on the flamethrower was one of Mr. Tribe’s inspirations to develop a more reliable product to join two pipes together, thus the Victory Joint emerged.

On 4 April 1919, Lt Tribe filed the patent for what is now known as the Victaulic coupling.

My invention is for an improved pipe joint which obviates the necessity for raising flanges at the ends of the pipes to be joined. I do not attempt to butt the ends of pipe together in order to form a fluid-tight joint, either with or without a packing ring between, but employ instead one packing ring made of flexible material, the form of which is an essential feature of the invention.
Tribe U.K. Patent 149,381 filing – 4 April 1919.[13]

Shortly thereafter, the Victory Pipe Joint Co. was established in London, England and a second patent was filed in both names. Dr Hele-Shaw had numerous inventions including the multiple-plate clutch, stream-line filter, variable-pitch propeller, and Victaulic pipe joint. Dr Hele-Shaw was an enthusiast for inventing as well as an educator, engineer, pioneer, motorist, and sportsman.[14] Later, in 1922, the words"Victory" and "Hydraulics” were combined and shortened to form a single word, Victaulic. Subsequently, Victaulic Company of America was founded in New York City in February 1925.

WWII-Field installation With Victaulic couplings

The concept of joining pipe with bolted mechanical couplings quickly gained popularity throughout World War II. The Victaulic coupling was used by Allied forces to accelerate the distribution of fuel and water to the troops. The coupling was invaluable for the troops because it decreased the difficulty of assembling and de-assembling pipe lines and allowed them to hasten distribution. The early installations of the Victaulic pipe joints included systems that needed flexibility; systems withstanding vibrations, shifting of soil, or other external influences. Victaulic fittings were very economical on space and were valuable in tunnels,ship work, and borings. The demand for dependable pipeline systems increased during World War II in direct correlation to the troops needing oil and petroleum. The earlier methods of distributing petroleum during war included shipping it overseas and dispersing by tank car, truck, or rail.[15]

Realizing the potential of pipeline systems, the War Department approved the request by the Quartermaster Corps proposing a new gasoline dispensing system on February 26, 1941.[15] “The Quartermaster Corps proposed to develop a pipeline as the primary means of delivering gasoline from tank cars to can and drum refilling points whenever tank trucks were not available or wherever features of terrain made the use of trucks impractical. All pipe, pumps, engines, hose, tools, and Victaulic couplings were standard commercial design.”[15] Victaulic couplings or similarly designed couplings, consisting of a synthetic rubber gasket held in place by two semicircular metal castings, were used to assemble pipelines that would establish fuel dumps to the front line and keep the troops well supplied.[15]
