Seal replacement on ABB IRB 4600 robots during maintenance, overhaul or leak repair.
Planned preventive maintenance and re-sealing programmes that renew seals before they start to weep.
Restoring sealing integrity on IRB 4600 joints that show leakage or contamination ingress.
Supporting long-term serviceability of installed IRB 4600 cells with genuine-size seals.
Spares provisioning for maintenance teams that would otherwise wait on a full assembly.

Provide the catalog-specified sealing element so a joint can be resealed to the ABB specification.
Match the specified size and material — "Nitrile rubber 188 x 2" — so the joint regains its designed sealing performance.
Let maintenance teams renew a low-cost wear item instead of replacing a whole assembly.
Turn an unplanned leak into planned maintenance work.

Safety & Installation Notice

Isolate and lock out the robot before opening any sealed joint, and release stored energy following the ABB service procedure.
Confirm the size before fitting. The 3HAB3772-xx family contains many look-alike codes with different sizes — verify the full article number 3HAB3772-129 against your spare-parts list.
Never reuse a removed O-ring. Nitrile seals take a compression set, so a used ring will not seal reliably.
Clean the groove and mating faces thoroughly and remove every fragment of the old seal.
Fit without sharp tools to avoid nicking the new ring or scoring the sealing surfaces, and make sure the ring is not twisted in the groove.
Check that nitrile rubber suits the media and temperature range of your application before installation.
Store the ring away from heat, direct sunlight and ozone, and keep it clean until fitting.
Check the joint for leaks after reassembly before returning the cell to production.

Wrong size code: a neighbouring 3HAB3772-xx article has a different inside diameter or cross-section and will leak.
Short-code ordering: quoting "3HAB3772" without the -129 suffix almost always results in the wrong seal.
Reused seals: refitting a removed O-ring that has already taken a compression set.
Fitting damage: nicks, cuts or a twisted ring creating an immediate leak path.
Dirty groove or sealing faces leaving a leak path despite a new seal.
Material misuse: nitrile exposed to incompatible media or temperatures hardens, swells or cracks.
Wrong location: fitting this article into a joint it is not specified for, since the catalog does not state the location.
Ageing in storage: elastomer kept hot or in sunlight degrades before it is ever fitted.

Genuine ABB O-ring verified by full article number 3HAB3772-129 and type designation "Nitrile rubber 188 x 2".
We check the neighbouring codes in the 3HAB3772-xx family so you do not receive a look-alike size.
Size, material and location confirmed against your parts list before we quote.
Supplied as new original or used original; we confirm the condition with you before you order.
Small critical part handled properly: clean packing and worldwide shipping from Shanghai via DHL / FedEx / UPS.
Inquiry-based supply: send your robot serial number and spare-parts list and we match the correct seal.
