So a machine operator on an oil rig or factory floor is torquing down a fitting on high-pressrue hydraulic line, and a captive seal mating perfectly with a BSP thread is the only thing keeping 3500 PSI from spraying hydraulic fluid everywhere, that's exactly what these combination joints were made for.
We build them from medium carbon steel that's been galvanized, so corrosion resistance in that salt-spray enviornment is actually pretty solid, and the hexagon head takes a standard wrench without any fuss.
The pressure rating sits at 6000 PSI (we've tested them higher), and you've got a temperature window from -20°C to +120°C—it handles hot oils fine but you wouldn't spec them for a steam line.
Anyway, they're female-threaded with BSP configuration (1CB-WD/DB-WD or RN variant), and we're pushing about half a million units a month out teh door, so lead time is usually 20 days or so but confirm it before placing a custom order.
You'll pay a bit more than a standard compression fitting, and that captive seal makes assembly slower than a simple O-ring joint, (most buyers already know they're swapping longevity for speed here).
One thing—we stock these in both ISO and SAE thread profiles, but the SAE tolerances are tighter than DIN on this hex head, so double-check which your spec sheet calls for if you're retrofitting existing gear.
We can do as few as 100 pieces for standard sizes, but if you need a custom thread or finish, MOQ jumps to 500.
Yes, we include material certificates and test reports for every batch. Just let us know if you need ISO or DIN compliance docs with your shipment.
We can do zinc-nickel or black oxide, but it'll add about 5–7 working days to the lead time. Standard galvanized runs about 15 days from order.
Keep them in a dry, cool place away from direct sunlight. The seals are nitrile rubber, so temperatures above 50°C or ozone exposure can degrade them over time.
They're designed for BSP female ports, so they'll work with SAE 100R1 and R2 hoses as long as you use the correct adapter or hose end. The 6000 PSI rating covers most medium-pressure systems.
