The best 3/8 x 38 V-belt depends on the machine and drive it must fit. The uxcell 3L380 is a general-purpose classic wrapped option, while the Honda replacement belt and Kubota cogged belt name specific equipment applications. For lawn and garden use, the uxcell 3LK380 is identified as an aramid cord belt; for industrial drives, the PIX 3VX380 is listed for several types of machinery. Confirm the belt profile and equipment part number before choosing, since the same nominal width and length do not guarantee interchangeability.

uxcell 3L380 Classic Wrapped Rubber V-Belt
This belt is a general-purpose option for a drive that calls for a 3L-profile belt with a 3/8-inch width. Its listing specifies a 38-inch (965 mm) outside circumference and a 7/32-inch height, providing useful dimensions to compare against the old belt or equipment documentation.
Best for: Buyers replacing a classic wrapped belt when the machine specifies the 3L profile and the listed dimensions. It was selected as a straightforward match for the search’s nominal size.
Limitation: The listing does not identify a specific mower or machine model. Do not assume that “38 inches” alone confirms a fit; verify the required profile and measurement type.
Honda 3/8 x 38 Mower Drive Belt
This replacement drive belt is listed for Honda HRR216 and HRT216 walk-behind mowers and names Honda part number 22431-VG3-B50. That model and part-number information makes it more application-specific than a belt described only by size.
Best for: Owners of the named Honda mower models who are checking a replacement against the equipment’s part number. It was selected because its listing directly connects the 3/8 x 38 size to particular walk-behind mower applications.
Limitation: The listing names particular models and a part number; it does not establish fit for every HRR216 or HRT216 variation. Check the mower’s parts information before ordering.
uxcell 3LK380 Aramid Cord Belt
The uxcell 3LK380 is described as a gray cord belt for lawn and garden mower decks. The listing gives its dimensions as 3/8 x 38 inches and identifies aramid cord. Those details can help buyers distinguish this option from a classic wrapped 3L belt or an industrial 3VX belt.
Best for: Buyers seeking a 3/8 x 38 belt specifically described for lawn and garden mower decks. It was selected for its stated application and cord material.
Limitation: The listing information provided does not specify mower models or a replacement part number. Confirm the machine’s belt designation instead of relying only on the stated size.
PIX 3VX380 Cogged Industrial V-Belt
This PIX belt is identified as a cogged 3VX380 industrial drive belt with a 3/8 x 38 designation. Its listing names compressors, pumps, blowers, generators, vacuum systems, heat exchangers, and heavy-duty power transmission as intended applications.
Best for: Buyers whose industrial equipment calls for a 3VX cogged belt. It was selected because its listing describes both the profile and a range of industrial drive uses.
Limitation: A 3VX profile is not automatically interchangeable with a 3L or 3LK belt. Choose it only when the equipment specification calls for the appropriate profile.
Cogged Fan Belt for Kubota Equipment
This 3/8 x 38 cogged fan belt listing names Kubota part numbers 14351-74050, 16206-97010, 16206-97012, and 16206-97013. It also lists equipment including the B26, B3000, B3030, B3350, RTV1140, RTV-X1140, and RTV-X112.
Best for: Buyers comparing a replacement belt against the listed Kubota part numbers and equipment models. The specific application references make it more targeted than a size-only belt listing.
Limitation: The long application list does not confirm compatibility with every machine configuration. Match the installed belt or equipment parts information to the listed part numbers.
Buying Guide: How to Choose a 3/8 x 38 V-Belt
Does the belt profile match the machine?
Start with the profile, not just the width and length. These options include 3L, 3LK, and 3VX designations. Similar nominal dimensions do not mean the belts share the same cross-section or intended drive. Use the belt designation in the equipment manual, parts list, or marking on the original belt whenever available.
What does “38 inches” measure?
Listings may describe a belt by outside circumference, nominal size, or a model designation. The uxcell 3L380 listing explicitly states a 38-inch outside circumference. If the old belt’s measurement was taken differently, the numbers may not compare directly. Check the machine specification and the listing’s stated measurement before buying.
Should you choose a general belt or a model-specific replacement?
A size-based belt can suit equipment that specifies the same size and profile. A model-specific listing can make comparison easier when it names the machine or original part number. For Honda and Kubota options, verify the listed model or part number against the equipment documentation rather than treating the product title as universal fitment.
What material or construction details matter?
The product names distinguish a classic wrapped rubber belt, an aramid cord belt, and cogged belts. These descriptions help narrow a search when they match the machine’s requirements, but they do not replace the equipment specification. Avoid selecting a belt based on construction terminology alone when the correct profile is unknown.
