For a fleet maintenance shop swapping out leaky JIC connections on a dozen excavators, the pricing on these SAE O-ring seal fittings makes the switch pretty much a —sample pricing for a single unit is around $4.50, mid-volume for 50 pieces drops to about $3.20 each, and bulk orders over 500 can land closer to $2.80 per fitting.
They're medium carbon steel with a galvanized finish, which holds up well in the -40°C to +120°C range we see on hydraulic systems, and the presure rating goes up to 420 bar—so for most construction equipment circuits, that's more than enough headroom.
The size range covers 1/4" to 2", and you can get male or female threads with O-ring, flat, cone, or multiseal options, but what it does is let you standardize across DIN, ANSI, GB, and JIS standard without juggling multiple supliers.
One thing though—these aren't ideal for high-vibration application like hammer attachments unless you add thread-locker, because the O-ring seal can shift under extreme shock loads (usually 2-4 weeks lead time on custom thread combinations, but standerd sizes ship in 5 days).
Also, the color options are silver, yellow, or white depending on zinc plating thickness, which is just a cosmetic thing but some buyers have preferences for their shop inventory.
MOQ is negotiable, so you can order 10 pieces for a prototype test or 1,000 for a production run—just confirm lead time on bulk because of that it can stretch to 30 days.
Yes, the 420 bar rating applies to the full size range, but keep in mind that actual working pressure can depend on thread type and assembly torque. We recommend checking the specific fitting size against your system’s peak pressure.
We can include both certificates with your order upon request. Just let your sales rep know at the time of booking, and we’ll attach them to the packing documents.
Lead time ranges from 5 to 30 days depending on quantity and any special thread or coating specs. For standard sizes with our stock materials, we usually ship within 10–15 days.
Each adapter is designed with a single seal type per end, but we can produce fittings with different seal types on each side. Let us know your exact requirements, and we’ll confirm feasibility and pricing.
We offer silver (clear zinc), yellow (gold passivate), and white (blue zinc) as standard. The silver is most common for construction equipment, but we can run any of the three on your order with no extra lead time.
