Hydraulic Oil Filter – HH Series Extension (HHTAO-59900 / HH160-32093)

Following the HH150-32430 logged last batch, these two P/Ns extend the DE-origin industrial hyd OEM's HH family — the same house that carries 405/406/409………(utility hyd packs) and 6211472xxx(lube carts). HH = pressure-line / return-line hydraulic filter series from this OEM, DIN-threaded heads, FKM default, collapse 21/31 bar class.

HH160-32093 — Pressure/Return Cart, 160 L/min Class

HH150 + HH160 together = one utility hyd pack skid likely has 2 HH positions (e.g., smaller loop = HH150, main loop = HH160; or 2 redundant packs: Pack A=HH150, Pack B=HH160). BOM qty per PN = authority: if HH150 qty=2 + HH160 qty=2 → 2 packs (one HH150 + one HH160 per pack, or 2×HH150 + 2×HH160 = 2 packs each 2 positions). If HH150 qty=1 + HH160 qty=1 → 1 pack with 2 HH positions (small loop + main loop on same skid — common on gate-hyd or crane-hyd where a smaller auxiliary circuit feeds the clamp/lock and main circuit feeds hoist).

HHTAO-59900 — Not a Filter Element (Attachment/Accessory)

HHTAO-59900breaks HH pattern:

• HH160… = filter cart (digits after hyphen = 32xxx media/length code)

  
  

• HHTAO-59900 = HH+ TAO+ 5-digit tail — TAO in this DE hyd OEM's catalog = Test Adapter / Thermowell / Alarm Orange? Or TA= Test Adapter (DIN test port with gauge nipple, M16x2 or 1/2" BSP on HH head), O= Option (with protective cap / with schräder).

  
  

More precisely in this OEM's HH-series accessories:

• HH… heads have a 2mm test port (DIN 2353) for ΔP gauge — the adapter to convert that to a readable gauge nipple or to a transmitter is a TA-coded spare (qty=1 per head, permanent, order only OH)

  
  

• TAOspecific = Test Adapter, Option = with dust cap + chain, or with orange indicator button (visual clog tell)

  
  

• 59900 = 5-digit tail (accessory P/Ns in this OEM run 5xxxx, while filter carts run 32xxx — that's the split)

  
  

So HHTAO-59900= test adapter / ΔP port accessory for HH-series heads (likely on the same utility hyd pack(s) where HH150/HH160 sit). Qty on BOM likely = 1 per HH head (so if 2× HH150 + 2× HH160 = 4 heads → HHTAO-59900 qty=4, or qty=1 if only one head instrumented).

Alternative read: TAO= Tank Adapter / Overflow? No, HH-series = pressure/return line filters (not tank breather — tank breather in this OEM is BF…or TF…). TA= Test Adapter is standard across DE hyd OEMs (ARGO-HYTOS, HYDAC, INTERNORMEN all use TA/TB/TC for test nipples). O= Orange (visual indicator button) or Option.

Traps — HH160 + HHTAO

Trap 1: HH160 ≠ HH150 — same family, different flow/collapse spec

H/OD ~280-300 vs ~250, flow 160 vs 150 L/min. If stores swaps HH150 elem into HH160 head → ΔP higher (undersized for 160 flow), head bypass may nuisance-open. If HH160 elem into HH150 head → OK on smaller flow but over-spend, and H may be slightly longer (300 vs 250) → may not seat (locator notch diff). Full PN + H/OD check = authority.

Trap 2: HHTAO-59900 = accessory (qty=1 per head), NOT consumable

Stores seeing "HH…" and ordering as filter element → wrong (it's a brass/nylon test nipple adapter, ~$20–50 vs element ~$80–150). BOM description = "Adapter, Test, HH Head" vs "Element, Hyd, HH160" — authority. Qty: if HH160 qty=2 (2 heads) and HHTAO qty=2 → 1 adapter per head (normal). If HHTAO qty=1 and HH160 qty=2 → only one head instrumented (spare adapter on shelf, or only "A" head has gauge, "B" head blind plug).

Trap 3: HH-series heads = alphanumeric 7d (not logged yet in your BOM)

HH150/HH160 elements need permanent heads — P/N likely HH150-xxxxx(head) + HH150-32430(element) in this OEM's style (head and element share base HH150-, tail splits head vs elem). Or head = separate 7d not HHprefix (e.g., 62xxxxx-class head from same DE OEM — 62……… lube carts + HH……… hyd carts share same head family maybe). Search BOM for "HH150-" or "HH160-" head PNs (tail different from 32430/32093 — heads usually tail <10000, elements tail 32xxx). That head PN locks House #11 further (DE OEM: 40… hyd packs + 62… lube carts + HH… hyd carts + TAO… accessories).

Trap 4: FKM default — if utility hyd ever converted to HFD (phosphate ester, fire-resistant, e.g., near turbine lube reserve or fire-pump hyd)

FKM swells/cracks on HFD long-term → need EPDM/ED (dark-grey). HH-series offers NBR/EPDM options (tail split) — check if any HH150/HH160 in plant have EPDM variant logged (not yet). If utility hyd near fire-water pump house or turbine bay (fire-risk zone) → may be HFD, check fluid tag.

30-Second Field Lock

Near the utility hyd pack(s) (gate/crane/CW pump station — same area as 405/406/409 logged earlier):

1. HH160-32093 — on pack skid, near HH150-32430 (if 2 positions) or on separate pack (if 2 packs). Cast head: "HH160" + DE OEM logo + DIN 24° + "PRESSURE" or "RETURN" label. Element H ~280-300, OD ~115-125, old O-ring brown-red FKM.

   
   

2. HHTAO-59900 — on HH head's side (2mm test port, with a small brass/nylon adapter + dust cap, maybe orange button). One per instrumented head. If head has a ΔP gauge or transmitter nearby → TAO = test adapter for gauge. If head has visual clog button (orange pop-up) → TAO = that button assembly.

   
   

3. HH head PN — search BOM "HH150-" or "HH160-" for head (tail <10000). If head = HH150-1xxxx+ elem HH150-32430→ confirms this OEM's style (head/elem share base PN). If head = 62xxxxx(DE 7d) → HH carts use same head family as 6211472xxx lube carts (House #11 = DE filter OEM: 40…(hyd packs) + 62…(lube) + HH…(hyd carts) + TAO(accessories) — very coherent).

   
   

4. BOM qty — HH150 qty=? HH160 qty=? HHTAO qty=? → tells pack config (1 pack 2 positions vs 2 packs 1 position each vs 2 packs 2 positions each).
