If you ride orange—or the blue cousins—you already know how much grief a cheap oil filter can cause. This piece, officially described as “H IFLO HF655 KTM/HUSAB ERG/HUSQ VARNA OIL FILTER,” has quietly become a workshop staple. I’ve seen it on benches from garage racers to rally prep shops. It’s made in Xiangjiang Street South, Jinggangshan Road West, Qinghe County, Xingtai City, Hebei Province—where, oddly enough, there’s a cluster of very capable filtration factories. And yes, the finish looks tidy.

What it is, in practice

The Hi Flo H F655 Oil Filter KT M 770.38.005.001 - Husabe Rg Husqva Rna KTM 250/450/500/690 is a cartridge filter for KTM/Husaberg/Husqvarna singles (250–500 EXC/FE and the 690 platform among others). Many customers say it drops in cleanly, seals without drama, and—surprisingly—holds up after long dual-sport days.

Key specifications (approximate)

Media Resin‑impregnated cellulose + synthetic blend
Nominal filtration ≈ 20–25 µm (ISO 4548‑12 methods; real‑world use may vary)
Bypass valve ≈ 1.2 ± 0.2 bar (crack)
Burst pressure > 10 bar (bench tested)
Temperature range -20°C to 140°C (seal integrity)
Service life Follow OEM intervals; off‑road ≈ 10–20 engine hours, 690 dual‑sport ≈ 5,000–10,000 km

Fitment must be verified against your VIN and year. I guess that’s obvious, but still—do it.

How it’s built and tested

Materials: blended media, tin‑free end caps, nitrile seals. Methods: laser‑cut pleats, controlled cure resin, ultrasonic seam. QA includes multi‑pass dirt holding and Beta ratio checks (ISO 16889), efficiency per ISO 4548‑12, and bypass verification. Typical lab note I saw: β20 ≥ 200 and ≥99% capture at ≈20–25 µm under stabilized flow—good enough for hard enduro oils. To be honest, paper alone won’t cut it; the blend matters.

Where it shines

  • Single-track/enduro: frequent oil turns, high shear, lots of clutch dust.
  • Rally/ADV weekends: longer drains, heat cycles, sand ingestion risk.
  • Commuting: cold starts + quick heat—seal resilience matters.

Industries that buy in bulk: rental fleets, training schools, and municipal trail crews. Odd mix, but true.

Vendor landscape — quick comparison

Vendor Pros Watch‑outs
Pulongte (Hebei origin) Consistent batches, ISO‑aligned tests, fair pricing, bulk customization Lead times during peak rally season
OEM (KTM/HQV) Guaranteed fit, dealer support Higher cost, often identical spec media
Generic aftermarket Low price, easy availability Variable QA; bypass settings may drift

Customization and service

Private labeling, moisture‑resistant cartons, and batch CoCs are available. Certifications: factory aligns with ISO 9001 and applies ISO 4548‑12 protocols. Warranty is straightforward: material/workmanship. For drains—stick to your manual; in fact, KTM 250/450/500 off‑road intervals are hour‑based, while 690s can stretch much longer, conditionally.

Field notes and mini case studies

Desert rally bike (KTM 450): two-day stage, oil at 120–130°C peaks, post‑ride teardown showed no pleat collapse; bypass check OK. Commuter 690: 7,500 km mixed riding, UOA hinted low silicon and stable viscosity—filter didn’t skew pressure. Anecdotal? Sure. But consistent with lab numbers.

Customer feedback is mostly “fits first time” and “no glitter after muddy weekends.” However, a few riders noted packaging dents in transit—ask for reinforced cartons if you’re ordering bulk.
