Gun Drilling Unions
Talco, LLC’s gun drilling unions feature a passage size of over one-half inch, which provides a high fluid handling capacity to the rotary joint (sometimes also called a “swivel joint”). Our gun drilling unions also feature balanced sintered silicon carbide face seals. These high quality and durable balanced seals use external spring pressure to maintain a positive seal within the gun drilling union or joint. The operating pressure of the coolant will not affect the seal load. The gun drilling union is supported by ABEC 1 Radial Contact Ball Bearings. Our gun drilling union or joint also features a nickel-plated steel shaft and an aluminum housing.
