So you're running those excavators hard, and the thread on your 1JG9 fittings keeps galling or leaking under pressrue — we see it all the time, especially with subpar galvanizing that chips off, but the 20#/45# medium carbon steel core on ours handles the vibration better than most DIN-spec parts we’ve tested. 2. What it does is maintain a tight seal at the connection point where male thread meets the hose, which is where 80% of your hydraulic issues start on a heavy digger, and that round head just fits into tight spaces without stripping. 3. The galvanized surfce treatment (usually silver or yellow) adds roughly 200 hours of corrosion resisance before any rust shows up — this isn't ideal for marine environments, so stick to dry or land-based use. 4. Anyway, the 1JG9-08-06OG weighs about 0.2 kg per unit, packs into 60 per box, and we usually have stock for your MOQ of 500 or so, though lead time might hit 20 days during peak season. 5. For ordering, confirm your thread type (BSP or JIC) because the standard is just for DIN flat-face — double-check that spec against your couplers, and we’ll include the COA with HPLC-based testing on the zinc layer thickness.
Our standard MOQ is 60 pieces per box, but if you need a smaller trial order, just talk to us — we can often flex on that. Mixing different sizes in one order is possible, but each size will still need to meet its own MOQ.
Lead time is typically 7-15 days, depending on stock levels. If we have them in warehouse, we can ship within 3-5 days. For larger bulk orders, give us a heads-up and we'll confirm the timeline.
Yes, we can provide mill certificates for the 20# or 45# steel upon request. Just let your sales rep know beforehand, and we'll include them with your shipment.
The galvanized coating gives good corrosion resistance, which holds up fine for standard outdoor excavator work. If you're dealing with extreme conditions like saltwater or heavy chemicals, let us know — we might recommend a different finish.
They're packed in sturdy cardboard boxes with layers separated by foam or cardboard partitions. That keeps them from banging into each other and damaging the threads. For international shipping, we add extra outer packing.
