Why Contractors Choose It
- Listed for the applications stated on the Arlington spec sheet, so there are no jurisdictional surprises at inspection.
- Sealing washer and conduit ferrule designed to hold the IP rating after vibration and thermal cycling, not just on the inspector's first walk.
- Distributed by a Canadian-owned stocking dealer. Maple Electric Supply ships from Ontario, so the SKU lands on site without cross-border duty calcs or week-long customs holds.
- Backed by Arlington's North American manufacturing footprint. It's the same part number you've already spec'd on prior jobs, with the same listings.
- Replacement and add-on availability through a Canadian supply channel means short-notice job sites can pull additional units without re-engineering the order.

Installation Notes
- Liquid-tight conduit and fittings required in wet locations or where exposed to oil/chemicals. Must be listed for liquid-tight use per CEC 12-1300.
-
Primary code reference: CEC Section 12-1300 (Liquid-Tight Flexible Conduit); CEC 26-700 (Wet Locations).
- Verify the Arlington listing on the current spec sheet matches your local AHJ's adopted code edition. Provincial amendments to the CEC can override the federal base text.
- Confirm trade size, mounting style, and accessory pairing against the project drawings before ordering in volume. Maple Electric Supply's counter staff can pull the cut sheet on request.
- Installation must be completed by a qualified electrician where required by local code; the homeowner / unlicensed scope is narrower in Ontario than in several US jurisdictions.
Common Mistakes to Avoid
Patterns we see on returns, callbacks, and inspection re-visits around the Liquid Tight Fittings line. Most of them are small and avoidable when the right SKU and accessory get pulled at the counter.
- Using non-liquid-tight in wet locations
- Mixing PVC and metallic connectors on one run
- Skipping the sealing washer
- Forgetting concrete-tight rating in slab pours

Sourcing in Ontario
For contractors specifying the Arlington WH5 on a project, Maple Electric Supply can confirm in-stock counts before you commit on the bid. That's useful when the install window is tight or the substitution clause in the spec is closed. Larger orders qualify for project pricing, and replacement SKUs ship from Ontario stock instead of waiting on a cross-border backorder.
Frequently Asked Questions
-
Is the Arlington WH5 UL and/or CSA listed?
Arlington components are listed for the applications stated by the manufacturer. Always verify the listing on the product's spec sheet against your jurisdiction's adopted code.
-
Is this part made in the USA?
Arlington Industries manufactures the bulk of its catalog in the United States. Confirm origin on the current spec sheet if it matters for your project.
-
Trade size?
The WH5 is a 1-1/2" trade-size fitting.
-
Straight or 90° angle?
Varies by configuration. Check the WH5 datasheet for the exact dimensions, ratings, and accessory list before ordering in volume. Arlington updates spec sheets periodically, so spec the live version from the manufacturer's site for the current job.
-
Metallic (zinc die-cast) or non-metallic (PVC)?
The WH5 datasheet is the authoritative source on this. Arlington publishes torque specs, listed conductor ranges, and accepted accessories per part number, and those values shift between revisions even when the SKU stays the same.
-
Concrete-tight rating?
Confirm against the published Arlington WH5 cut sheet; values shift between configurations even inside the same family. Maple Electric Supply can email a current copy on request and flag any recent revisions that changed listed ratings.
-
Listed for outdoor / wet locations per CEC 26-700?
Maple Electric Supply can pull the WH5 spec sheet on request. Answers here depend on the specific configuration and the listed conditions of use, and anything that affects code compliance should come straight from the manufacturer's current published documentation.
