KPL Industry — high pressure fittings, certified four ways.
A South Korean manufacturer of high pressure valves and fittings for drilling, oil and gas, power generation and shipbuilding. We stock the compression fittings, ferrule fittings and check valves — backed by ISO 9001, ISO 14001, PED approval and a RINA workshop certificate.
What we stock from KPL
Three lines, all high pressure.
Compression fittings
High pressure compression fittings for hydraulic tube — the connection that seals on the tube itself rather than on a thread.
Compression fittings →Ferrule fittings
Ferrule fittings where a cutting or gripping ring makes the joint — repeatable, and re‑makeable on site.
Ferrule fittings →Check valves
High pressure check valves for one‑way flow, protecting pumps and holding load in circuits that must not backfeed.
High pressure check valves →The certificates, and what each one covers
- ISO 9001 — the quality management system behind the production process.
- ISO 14001 — environmental management.
- PED approved — the European Pressure Equipment Directive, which is what a European or European‑specified project will ask for.
- RINA workshop certificate — a classification society approval of the workshop itself, which matters on marine and offshore work.
Ask us for the current certificates with your quotation and we will send them with it, rather than after you have asked twice.
Where it gets used
- Drilling — high pressure lines where a fitting failure is not an option.
- Oil and gas — process and hydraulic circuits needing documented material and pressure ratings.
- Power generation — instrument and control tubing at pressure.
- Shipbuilding — where the RINA workshop certificate does real work at survey.
KPL runs a documented ten‑step production sequence, with raw material checking as its own stage rather than a final inspection.
KPL does not have a published catalogue in our library yet. Tell us the size, the pressure and the tube OD and we will send the datasheet for the exact part.
Comparable lines we do hold catalogues for
If you are still choosing, these cover the same connection types and are published:
- High pressure fittings — 11 catalogues, including RFS, HSME, Eaton and Both‑well.
- High pressure valves — 13 catalogues, including MHA Zentgraf to 700 bar.
We will tell you honestly where a published equivalent is the easier specification, and where KPL is the right call.
Send the size, the pressure and the tube OD.
