Topaz Lighting 111MHDG Rigid Offset Nipple, Malleable Iron, Hot-Dip Galvanized

The Topaz Lighting Rigid Offset Nipple is a malleable iron fitting engineered to enable easier direction changes or slight elevation adjustments where rigid conduit enters boxes or enclosures. This family is available in trade sizes from 1/2" through 1-1/2", with the 1-1/2" size offsetting the raceway axis by 3/4". Strengthened through a Hot-Dip Galvanizing (HDG) process, every size in this offset nipple line shares the same malleable iron body and smooth interior bore, which facilitates wire pulling and helps prevent abrasion damage to conductors during installation.

Key Features

  • Trade Size: Available in 1/2" through 1-1/2" trade sizes, suitable for rigid conduit raceway systems requiring an axis offset at boxes or enclosures.
  • Offset Dimension: Engineered axis offset (3/4" on the 1-1/2" size) that enables direction changes or slight elevation adjustments without additional fittings.
  • Durable Construction: Malleable iron construction provides exceptional strength and impact resistance for demanding commercial and industrial environments.
  • Hot-Dip Galvanized Finish: The dip galvanizing process ensures long-term corrosion resistance and maintains the structural integrity of the fitting throughout its service life.
  • Smooth Interior: A smooth interior bore facilitates wire pulling and protects conductors from abrasion damage during installation.
  • Conduit Type: Designed for use with rigid conduit (RMC) systems entering boxes or enclosures.

Technical Specifications

  • Product Type: Conduit Nipple
  • Conduit Type: Rigid/IMC

Typical Applications

  • Rigid conduit raceway systems requiring axis offsets at junction boxes or enclosures
  • Commercial and industrial electrical installations
  • Conduit entry points at panelboards, pull boxes, and electrical enclosures
  • New construction and renovation wiring projects
  • Applications requiring slight elevation or direction changes in conduit runs

Why Topaz Lighting?

Topaz Lighting's Rigid Offset Nipples are manufactured from malleable iron and processed through a Hot-Dip Galvanizing treatment, delivering the corrosion resistance and mechanical strength required for reliable, long-lasting performance across the full 1/2" to 1-1/2" size range. The smooth interior bore reflects Topaz Lighting's commitment to installer-friendly design, reducing wire-pulling effort and protecting conductor insulation. Electrical professionals trust Topaz Lighting fittings for code-compliant conduit systems in commercial and industrial applications.

Topaz Lighting 111MHDG – Frequently Asked Questions

1) What trade sizes do the Topaz MHDG offset nipples come in?
The Topaz hot-dip galvanized offset nipple line spans 1/2 inch through 1-1/2 inch trade sizes. The orderable sizes are 1/2 inch (111MHDG), 1 inch (113MHDG), and 1-1/2 inch (115MHDG). Match the trade size to the rigid conduit you are terminating, not to the knockout, since the fitting threads onto the raceway.
2) How much does the Topaz 115MHDG offset the conduit axis?
The 1-1/2 inch size (115MHDG) shifts the raceway axis by 3/4 inch. That is the number to check against your enclosure spacing before you order, because the offset is fixed in the casting and cannot be adjusted in the field. If your knockouts are further apart than the offset allows, you need a nipple and a pair of bends instead.
3) Can I use this offset nipple on IMC, or is it rigid only?
It is listed for Rigid/IMC, so it works with both rigid metal conduit and intermediate metal conduit. Both use the same threaded connection, so the fitting mates the same way on either. It is not intended for EMT, which is not threaded.
4) What is a rigid offset nipple actually used for on a conduit run?
An offset nipple lets rigid conduit enter a box or enclosure when the raceway axis does not line up with the knockout. The Topaz 111MHDG family is a malleable iron fitting with a built-in bend, so you get a small direction change or slight elevation adjustment at the box without adding couplings, chase nipples, or a field-bent piece of conduit. Typical spots are panelboards, pull boxes, and junction boxes where two enclosures sit close together but their knockouts are not on the same plane.
5) Is hot-dip galvanized malleable iron suitable for outdoor or wet locations?
Hot-dip galvanizing is the heavier zinc coating used on fittings that see weather, washdown, or corrosive industrial air, and it is what these Topaz offset nipples carry as their finish. Combined with the malleable iron body, that is the combination specified for exterior runs, parking structures, water treatment, and similar wet or corrosive environments rather than a plated zinc fitting.
6) Do I order this by the knockout size or the conduit size?
Order by the trade size of the conduit. A 113MHDG is the 1 inch fitting and threads to 1 inch rigid or IMC on both ends; it is not a reducer. If your enclosure knockout is a different size than the raceway, you need a separate reducing bushing or washer set in addition to the offset nipple.
7) Is the malleable iron offset nipple different from a steel chase nipple?
Different jobs. A chase nipple is a straight short threaded piece for joining two enclosures back to back. These Topaz fittings are offset nipples, cast in malleable iron with a built-in axis shift so the two ends do not sit on the same centerline. If your boxes line up, use a chase nipple; if they are stepped, the offset is what closes the gap.
8) Will the wire pull through an offset nipple without damaging the conductors?
The bore is smooth through the offset, which is the point of using a cast fitting here rather than a tight field bend. It reduces drag on the pull and keeps the conductor insulation off any sharp transition. On a short offset like this the bigger limit is usually your overall bend count on the run, not this fitting.
