1) V3045V1H15— Return-Line Filter Element

What it is

A disposable pleated filter element for a pipe-mounted return canister (clamp-band bowl, flow arrow on the head). Oil has passed through the actuators and is returning to tank — this element guards tank cleanliness.

• V3045 = housing family and size class (fixes outer diameter, height class, and centre-tube)

  
  

• V1 = Viton (FKM) seal — O-ring will be brown/reddish, not black. This matters: if your system temperature or fluid type calls for Viton, do not swap to a black NBR spare.

  
  

• H15 = 15 µm filtration (beta-rated glass-fiber/synthetic — finer than the 10/20/25 you've seen elsewhere)

  
  

What to check before fitting

• Read the filter head nameplate near the pipe ports: should show the V3045… model, pressure rating (return class), port size, and a FLOW ARROW.

  
  

• Ruler-check: new element height / OD / centre-hole matches the old one.

  
  

• O-ring colour: brown/red (Viton) — if you pull a black one from stock "because it's the same box," stop. V1 = Viton by design.

  
  

Replacement steps

1. Stop pump → vent/bleed until pressure = 0.

   
   

2. Support the bowl — don't let it hang on piping.

   
   

3. Clamp off → pull element straight out → check bowl bottom for bright metal shavings (wear warning).

   
   

4. Wipe seal lands → thin film of clean hydraulic oil on the O-ring (no grease).

   
   

5. Seat element square on centre support tube → close vent slowly → ΔP indicator green, no seep.

   
   

Procurement wording (safe)

"V3045V1H15 — Return-line element for V3045-family housing (V1 = Viton seal, H15 = 15 µm). Confirm against head nameplate; require OD / height / centre bore / seal compound before delivery. Do NOT substitute with an NBR-seal version."

2) 5234-0105— Internal Stock / Material Number

What it is

A plant stock/material number (ERP/bin number). Digits alone don't tell you micron, seal, or dimensions — the only safe authority is the filter housing it belongs to.

How to qualify it (one minute)

• Check the bag/bin label (or BOM line): does it say "element / cartridge" or "seal kit / repair kit / O-ring kit"?

  
  

• If element: carry it to the filter, read the housing nameplate (model + ports + pressure + flow arrow), and ruler-check height / OD / centre-hole against the old element.

  
  

• If kit: use only for the equipment the BOM states — not as a filter element.

  
  

Procurement wording (safe)

"5234-0105 — Internal stock/material No. — issue against the equipment tag / housing model written in the BOM. If supplier delivers an element, require housing model + OD + height + seal compound first; if a seal/repair kit, issue only that specified kit."

3) PH718-11-CNVGE— Pressure-Line Filter Element

What it is

A disposable pleated element in a heavy cast-steel head on the pump-discharge leg (between pump and valves). High-pressure position — trapped pressure is hazardous.

• PH718 = pressure filter family (head near ports will show this)

  
  

• 11 = longer/higher-dirt-holding length class in the 718 family

  
  

• CN = C = NBR base (black/dark grey) + N = end-cap/bypass variant

  
  

• VGE = V flags a higher-temp/compound nuance; GE = equipment/project tag (tells Stores which machine)

  
  

If the old O-ring looks brown/reddish, the "V" in the suffix is telling you why — do not force a plain black NBR "C" spare without confirming the fluid/temperature spec.

Replacement — pressure-side (extra care)

1. Close upstream isolation if fitted → bleed slowly at the head vent until gauge = 0 bar and no hissing.

   
   

2. Support the bowl — heavy hardware; don't hang on piping.

   
   

3. Release retainer → lift element straight out (follow the flow arrow on the head).

   
   

4. Check bowl bottom for bright metal shavings (pump/valve wear — report).

   
   

5. Wipe seal lands → thin film clean hydraulic oil on O-ring (no grease).

   
   

6. Seat square on centre support (off-centre under pressure = bypass or crush).

   
   

7. Torque evenly → close vent → pressure up slowly → watch leaks.

   
   

Procurement wording (safe)

"PH718-11-CNVGE — Pressure-line element for PH718-family housing (11 long length, CN = NBR base + N variant, V = compound nuance, GE = equipment tag). Supply exact match confirmed against head nameplate; require OD / length / centre bore / seal compound before delivery."

4) One-Line BOM (copy-paste)

• V3045V1H15— Return-line element, V3045 family, 15 µm, Viton seal (V1 = brown/red), fits V3045 head nameplate only

  
  

• 5234-0105— Internal stock/material No. — confirm from housing nameplate / bin tag whether element or kit before use

  
  

• PH718-11-CNVGE— Pressure-line element, PH718 family (11 long length), NBR base + N variant, V-nuance, GE = equipment tag — fits PH718 head nameplate only, full depressurize

  
  

One rule that covers all three

V3045 = vent until 0, watch the brown O-ring (Viton, not black).

5234 = digits alone mean nothing — the housing nameplate decides.

PH718 = bleed until gauge is zero, support the bowl, seat square, pressure up slow.

If paint hides the nameplate, stand the old element upright, ruler against it, write H = ___mm / OD = ___mm on the BOM line — that makes every spare "idiot-proof" without a single brand name.
