A hammer union comprises of a thread end, a nut end and a hammer nut which, when cinched up, compresses a composite seal assembly thereby preventing leakage. The seal assembly comprises a metal insert of a size to pass into the seal groove of conventional hammer unions and a small seal acting between the insert, the thread end and the nut end. The small seal is conveniently an O-ring or a Hammer Union Seal (Lip Seal) and is of a size that is compressed when the seal assembly is inserted into the thread end of the hammer union, thereby preventing the seal assembly from falling out of the threaded end when it is inverted.
Some profiles such as Fig 2202, Fig 1004, Fig 1502, Fig 2002, Fig 602, Fig 1002 etc require a Hammer Union Lip Seal or an 'O'Ring depending on the Size of the Hammer Union.

Well Service Packing was developed to eliminate extrusion and provide excellent abrasion resistance for fracturing, acidizing, and cementing pumps; and it delivers maximum sealability for high-pressure well service pumps. We produce well service packing replacements for mud pumps. The pressure rings, header rings and female adapters are designed to retrofit current plunger sizes and designs. we deliver superior quality materials and workmanship to keep your equipment running longer. In addition custom machined shapes (lantern rings, spacers) can be engineered to meet your total sealing system requirements.
We manufacture well service packings in a wide variety of materials to suit specific well conditions and operating parameters, including |

Vee Packings/multiple Lip Chevron Packing sets seal static for valves and pumps/FKM ,NBR OR PTFE Hydraulic packings and seals Multiple-lip (chevron) Seals or Vee Packings that consist of a group of endless rings and are usually used for sealing rods, pistons, plungers in hydraulic cylinders and hydraulic presses. V-Packings are used for low or high pressure applications with Single or Double acting cylinder. V-Packings are also used in various Oilfield Downhole equipment such as various Valves etc. V-Packings are extremely suitable for usage in medium to heavy duty applications. Vee Packings accept low and high pressure while operating in the most extreme conditions and also if there exists any misalignment between the sealing gaps. The hinge-line action of Vee-Packings that enables immediate reaction even to minor pressure changes is very distinctive and exclusive to a Vee-Packing design. Each individual lip of a Vee-Packing set reacts independently to pressure thus effecting aseal automatically. In case of multiple lip configurations, pressure is automatically distributed thus effecting a seal along the shaft. Vee-Packings also premit automatic reaction to shocks from high pressure and overloads. The Vee-Packing is a combination of Base Seal, the Vee-Ring at the center and the Pressure ring. The Vee-Ring is the main seal that can retain high and low pressures while the base seal supports the center ring from getting extruded during high pressure applications. The Pressure Ring helps in retaining the Vee Packing profile and distributing pressure equally. |

Oil And Grease SealsOil seals - often called grease, fluid or dirt seals - close spaces between stationary and moving components in mechanical equipment, helping prevent lubricant escape. They also stop harmful contaminants from entering machinery, particularly in severe environments. Vital components of practically every type of machine and vehicle in operation, oil seals protect all types of precision-constructed, close-fitting ball, sleeve and roller bearings. In precision bearings, oil seals help prevent lubricants from escaping the bearings or a specific area. In machine components, oil seals help prevent abrasives, corrosive moisture and other harmful contaminants from entering machinery. They also help stop intermixture of two different mediums, such as lubricating oil and water. |
