Steel Nipples


Product Specifications
Welded steel pipe nipples both galvanized and black in diameters ranging from 1/8” up to 4” in lengths from close to 12” and cut-pipe up to 120”.

Technical Specifications

  • Standards:
    Product complies with ASTM A-53, A-733 and ANSI B1.20.1 for threading, dimensions and pipe specifications.
  • Pipe:
    Complies with ASTM A-53 mill tested schedule 40 and 80. Meets ANSI B36.1. All pipe is hydrostatic tested.
  • Galvanized:
    Zinc coating applied by hot dipped. Galvanized complying with ASTM A-123.
  • Black:
    Protected against oxidation with varnish coating.
  • Cutting Procedure:
    All pipe is roller cut. A visual inspection of seams, excessive galvanizing, mid-welds, poor galvanizing, bends, our of roundness, under and over weight of the pipe is made at the time it is cut. This is done for every length of pipe. Pipe lengths are cut to a tolerance of + or - 1/16” of the actual length.
  • Threading Procedure:
    All pipe is chaser thread cut to American Standard Tapered Pipe Thread standards. This is 3/4” taper per foot. Pipe is visually inspected for roundness of threads and other visual faults as it is removed from the threading machine.

Steel Magnetic Drain Plugs - NPT Threaded

Magnetic Drain Plugs are similar to standard pipe or straight thread drain plugs with one important difference - a permanent magnet is fastened to the plug body. This magnet attracts and holds abrasive, ferrous metal particles preventing their circulation through the lubrication or hydraulic system.

These abrasive, ferrous metal particles appear in lubricating or hydraulic systems as a result of the following conditions:
• The constant flaking effect of normal wear of moving parts.
• Particles not removed by flushing operations after boring or machining.
• Chipping due to sub-surface casting flaws.
• Minute component breakdown caused by stress usage.

Magnetic Drain Plugs prevent excessive wear to the system's components.

Magnetic Plugs are used by numerous manufacturers of gear boxes, transmissions, engines, and hydraulic systems for the automotive, aircraft, agricultural and machinery industries. Typical applications include:
• Outbound Engines
• Earthmoving Equipment
• Combines
• Balers
• Crawler Tractors
• Lift Trucks
• Mining Equipment
• Military Vehicles
• Turbine Engines
• Truck Axles
• Heavy-Duty Transmissions
