We keep these in stock across the smaller diameters — 1/4-inch and 3/8-inch are what most buyers grab, and lead time is usually 2-3 weeks for anything larger like the 1-inch. It's basically a forged carbon steel fitting with a hex head, so you can crank it down with a standdard wrench without stripping anything.
The inner cone gets a mirror polish, which for a hydraulic system matters more than you'd think — it drops turbulence in the flow path by a noticeable margin, and we've seen pressure drops improve by about 5-8 psi over unpolished equivalents. Working pressrue holds at 6000 psi for the smaller sizes, give or take, but you'll want to derate for the 1-inch to around 4500 psi in practice.
You're looking at a union, elbow, tee, cross, or bulkhead configuration, all threaded connections per DIN or JIS standard. Temperture range sits at -20°C to 200°C, so it's fine for most hydraulic loops, but don't push it with steam or anything above that upper bound — the galvanized surfce treatment starts degrading past 250°C.
Silver plating on the nut and a hardness treatment on the ferrule — that combination cuts galling during assembly, and we've had customers run 500+ cycles without the threads seizing. The tube itself comes fully annealed, so it bends without cracking if you're doing custom routing, but for high-vibration lines you'll still want the elbow or tee to keep stress off the joint.
MOQ is 50 units for standard sizes, and we usually have stock for 1/8-inch through 3/4-inch in the union and elbow styles. Cross and bulkhead are typically made to order, so confirm that lead time — it's about 20 days or so for those.
Also, the 1/16-inch size is a pain to handle — most buyers skip it for anything above 2000 psi because the wall thickness gets tight, so we don't stock it heavily. You'll get a COA with each shipment, but the HPLC data is only for the oil and gas compatibilty testing, not base media.
Up to 6000psi. That covers most hydraulic system demands, whether you're moving water, oil, gas, or even acids and bases.
Yes, we can issue mill test reports per DIN or JIS standards upon request. Just let your sales rep know what certificates you need.
Our standard MOQ is 1000 pieces per size and structure, but we can negotiate smaller trial orders for new customers—just ask.
Usually 15 to 25 working days after order confirmation, depending on the quantity and specific structures you need.
No special storage needed—just keep them dry and away from corrosive chemicals. The galvanized outer and polished inner are durable, but avoiding moisture helps maintain the look.
