When you're shopping for control cables, connectors, and I/O hardware, the connector you pick has to match both the power requirements and the environment. Do you need a weatherproof plug that can handle high current, or do you need a fast way to secure cable as it enters a junction box? The CHALITECK 63A 4-Pin Male & Female Industrial Waterproof Connector and the Arlington Industries 38AST Snap2 IT Connector Lot of 50 solve very different problems, so the right choice depends entirely on the job at hand.
Quick Verdict
If your priority is a durable, weather-resistant power connection, the CHALITECK connector is the one to get. If you're instead looking for a bulk supply of cable-to-box connectors for routing cable into boxes, the Arlington 38AST is the practical choice. Price matters here: the Arlington 38AST is priced at $52.26, which is 24% below the $69.00 CHALITECK unit, but the two products are not direct substitutes.

Where Each Product Wins
The CHALITECK wins in situations that demand a rugged, re-usable power connection with serious current capacity. Its sealed design keeps out moisture and dust, so it's a strong candidate for outdoor equipment, temporary power feeds, and industrial machinery. The included male and female ends make it a complete set for joining power lines.
The Arlington wins when you have many cable runs that need to land in boxes. The quick-connect mechanism speeds up installations, and you'll have enough fittings for multiple devices or a full job. It also costs less per connector, making it a smart buy for high-volume wiring work.
Product Notes
CHALITECK 63A 4-Pin Male & Female Industrial Waterproof Connector IP67 3-Phase IEC60309
For a connector that needs to hold up in harsh conditions, the CHALITECK 63A is built for the task. It's a 4-pin, 3-phase connector rated for 63 amps, and it carries an IP67 rating that speaks to its resistance to dust and water. The pin-style electrical plug provides a secure, positive connection, and because the set comes with both male and female ends, you have a complete pair ready to wire in. This is the more expensive option in this comparison, but you're paying for a purpose-specific industrial component rather than a general-purpose fitting. The flip side is that it's a single connector set, not a bulk package, so if your project involves many separate power points, you'll need to budget for multiple sets.
Arlington Industries 38AST 3/8\" Snap2 IT Connector Lot of 50
If your work centers on running cable into panels and boxes, the Arlington 38AST is designed to save you time. These zinc die-cast connectors feature an insulated throat and a tool-free snap-in mechanism: you push the cable into the fitting and then snap the fitting into the box. They're made for MC/HCF steel and aluminum cable, as well as AC/HCF cable, making them versatile for typical branch circuit wiring. The package size lets you keep a full job moving without running out, and the per-unit cost is much lower than the single CHALITECK set. The limitation is that these are accessories for cable termination, not sealed power plugs. They won't give you a disconnectable high-current connection, so they're not an alternative if that's the task you're trying to solve.
Final Choice by Use Case
Choose the CHALITECK 63A connector when you need a sealed, industrial-strength plug-and-socket connection that can be mated and unmated as needed. It's the right tool for outdoor or washdown environments and for portable industrial equipment.
Choose the Arlington 38AST when you're installing cable runs into junction boxes and want a fast, repeatable method with enough connectors to handle multiple fixtures. If you're looking for the lower upfront cost and you're dealing with standard cable-to-box connections, this option is the better fit for your budget and your workload.
