Crouse-Hinds EYS11 – Frequently Asked Questions

1) What size conduit does the Crouse-Hinds EYS sealing fitting come in?
The EYS sealing fitting is offered in nine hub sizes, from 1/2 inch through 3-1/2 inch: EYS11 (1/2"), EYS21 (3/4"), EYS31 (1"), EYS41 (1-1/4"), EYS51 (1-1/2"), EYS61 (2"), EYS71 (2-1/2"), EYS81 (3") and EYS91 (3-1/2"). Hubs are female, so they thread onto male conduit thread of the matching trade size. Order by the conduit trade size on the run you are sealing.
2) Can an EYS seal be installed horizontally, or does it have to be vertical?
Either. The EYS is rated for vertical or horizontal sealing position, so the same fitting works on a riser out of an enclosure or on a horizontal run through a boundary. That matters where headroom is tight and you cannot get a vertical drop above the seal.
3) Is the Crouse-Hinds EYS approved for Class I Division 1 hydrogen areas?
Yes. The EYS carries a Class I, Division 1 NEC hazardous rating and is Group B rated, which is the hydrogen group. That makes it usable in the classified areas of hydrogen production, chemical processing and refinery work rather than only in Division 2 or in the lower gas groups.
4) Do I need a female or male hub sealing fitting for my conduit?
The EYS uses female hubs, meaning it threads over male NPT conduit thread on both ends. That is the arrangement for a seal spliced into a threaded rigid or IMC run between two lengths of conduit. If your seal has to thread directly into the female hub of an enclosure or device body, a female-hub fitting like this one will not land there without a nipple or a male-hub style seal instead.
5) What code standard does the EYS sealing fitting meet for a plant inspection?
The EYS is built to NEC/CEC standards, so it satisfies both US National Electrical Code and Canadian Electrical Code sealing requirements for a Class I, Division 1 area. For a facility standardizing hazardous location hardware across US and Canadian sites, one part number covers both jurisdictions.
6) How much room do I need to fit a Crouse-Hinds EYS seal in a cramped conduit run?
Allow roughly 4.313 inches of height with a 1.75 by 1.75 inch footprint, plus room to get a hand and the packing fiber into the filling opening. The fitting weighs 1.575 lb, so it needs no separate support beyond the conduit itself on a short run.
7) Do I still need sealing compound and packing fiber with the EYS, or does it come with them?
The EYS is the fitting body only. A completed seal also needs the damming fiber and the sealing compound poured into the fitting, ordered separately by volume for the hub size, plus the correct thread compound for the conduit joints. Budget those into the job when you count fittings.
8) Where does the NEC require a seal like the Crouse-Hinds EYS to be installed?
Seals go where a conduit run enters an explosionproof enclosure containing arcing or sparking parts, and where a run crosses the boundary out of a Class I, Division 1 area into an unclassified one. The EYS is the Division 1, Group B fitting for those points, and because it seals vertical or horizontal it can be placed at whichever orientation the boundary actually falls on.
9) Is a Group B rated seal overkill if my area is only Group C or D?
No, it is the safe direction. Group B is the hydrogen group and covers the more easily ignited atmospheres, so a Group B rated fitting like the EYS is acceptable in the less severe groups as well. Plants running mixed atmospheres often standardize on the Group B fitting to keep one part number on the shelf for all their Class I, Division 1 seals.
10) Will a Feraloy iron sealing fitting hold up in a refinery or chemical plant environment?
Feraloy iron alloy is what the EYS body is made from, chosen for corrosion resistance and mechanical strength in industrial conditions, and it is the standard body material for hazardous location conduit fittings in refineries, chemical processing and paint operations. For continuously wet or highly corrosive service, plants often specify an added protective coating on top of the iron body.
