After years of only one source of reliable 100K psi tubing, GPP Extreme Pressure is happy to announce they have a reliable alternative. Following the difficulties of supplying our customers during the pandemic, we scoured the planet for a second source of 100,000 psi tubing to meet our customer’s needs. This new product called XT100 for its extreme life at

The attenuator on a waterjet pump intensifier pump plays a critical role in maximizing waterjet cut quality. When the intensifier shifts at the end of a stroke, the change in direction of the plunger/piston assembly causes a momentary loss of production of pressurized water. This manifests itself as a periodic drop in the cutting pressure output and often a degradation

While there are many ways to seal systems containing high pressure liquids and gasses, the most common method of sealing in high pressure plumbing is the use of conical metal to metal sealing. This method is particularly common in waterjet systems, both in the pump and in the plumbing carrying high pressure water from the pump outlet to the cutting

At GPP Extreme Pressure, we are dedicated to the meticulous manufacture of a wide array of high-quality fittings and accessories, engineered to meet the exacting demands of the waterjet and food processing industries. Our commitment to excellence is evident in every aspect of our products, starting with their ability to withstand extreme pressures of up to 66,000 psi (4,550 bar). Crafted

GPP Extreme Pressure takes pride in producing a comprehensive line of high-quality adapters tailored for the waterjet, food processing, and general fluid handling industries. Our adapters encompass a wide range of configurations, including male-to-male and male-to-female designs, accommodating various connection types such as NPT, BSP, JIC, O-ring Boss, hose barb, and compatibility with pressure specifications ranging from 20 ksi to

GPP offers highly engineered basic elements of any waterjet infrastructure, tubing, fittings, and valves. Ordinary plumbing systems can be successfully created with components available from hundreds of parts vendors. However, in high pressure systems, the source of componentry does make a difference. With GPP’s expertise in metallurgy, machining, and high-pressure engineering, you are assured of quality parts that will provide

The extreme water pressures used in waterjet equipment cause very large tensile (stretching) stresses at the wetted surfaces of the stainless steel high pressure parts. Repeated changes in these pressure-induced stresses from normal pump operation will eventually result in formation and growth of metal “fatigue cracks” at these same wetted surfaces, causing part failure manifested by a dripping or spraying
