Crouse-Hinds CRS-53 57 Series Malleable Iron Hex Head Bushed Nipple, 3-Inch

The Crouse-Hinds CRS-53, part of the 57 series, is a 3-Inch malleable iron hex head bushed conduit nipple with a non-insulated throat, engineered to join conduit runs and fittings within rigid or IMC conduit systems. Built from malleable iron for strength and corrosion resistance, this bushed nipple features a hex head design for secure, tool-assisted tightening in tight enclosure and box connections. Electrical contractors and maintenance crews rely on this type of fitting to maintain a continuous, code-compliant conduit pathway while protecting conductors from abrasion at the connection point. As a recognized member of the Crouse-Hinds 57 series conduit nipple line, the CRS-53 is a dependable choice for professional installations that demand a durable, precisely sized connection between conduit and enclosure.

Crouse-Hinds CRS53 – Frequently Asked Questions

1) What trade sizes does the Crouse-Hinds 57 Series hex head bushed nipple come in?
Four trade sizes are offered on the 57 Series malleable iron bushed nipple: 3/4 inch, 1-1/4 inch, 3 inch and 4 inch. Order by trade size to match the conduit run and the enclosure hub you are landing in.
2) Can I use a Crouse-Hinds 57 Series bushed nipple on IMC conduit, or is it rigid only?
Both. The 57 Series bushed nipple is made for rigid and IMC conduit systems, joining two conduit sections or taking a conduit run into an enclosure, box or conduit body.
3) Does this Crouse-Hinds bushed nipple have an insulated throat for pulling conductors?
No. The 57 Series hex head bushed nipple has a non-insulated throat. The bushed shoulder gives a smooth, rounded entry that keeps conductors off a sharp edge, but there is no plastic or nylon insulating liner. If your spec or inspector calls for an insulated throat fitting, you need a different fitting.
4) Will a bushed nipple let me connect two runs of rigid conduit together?
Yes. A 57 Series bushed nipple is threaded on both ends, so it will tie two conduit sections together or run a conduit into an enclosure wall. Match trade size to the conduit on both sides, since the nipple is a single size through.
5) I need to standardize conduit entry fittings across a facility. Is the Crouse-Hinds 57 Series a single family across sizes?
It is. The hex head bushed nipples in sizes 3/4, 1-1/4, 3 and 4 inch all belong to the Crouse-Hinds 57 Series, same malleable iron body and same non-insulated bushed throat, so an MRO crew can stock one family and one install method across small branch entries and large feeder entries.
6) Why choose a malleable iron bushed nipple instead of a steel or die-cast fitting?
The 57 Series body is malleable iron, which gives impact resistance and holds up to wrench torque and rough handling in commercial and industrial work. That is the reason it gets specified over lighter die-cast fittings for panelboard and junction box entries and for conduit extension or repair work.
7) What is the hex head on a bushed nipple actually for?
The hex profile in the middle of the nipple gives a wrench flat, so you can torque the fitting down into an enclosure, box or conduit body instead of hand-tightening it. That matters in tight gear where you cannot get a strap wrench on a plain nipple, and it is how you get a tight, continuous metal path at the connection.
8) Do I need a locknut or bushing with a bushed nipple when landing it in a panel?
The bushed nipple itself is the threaded body with the bushed shoulder. Landing it through an untapped box or panel wall still takes the usual locknuts, and the bushed end is what protects conductor insulation at the entry. Into a tapped hub, the nipple threads straight in and the hex head gets wrenched tight.
