Haelok

What Haelok does

HAELOK AG is a privately held Swiss industrial manufacturer headquartered in Schlieren, founded in 2005, that designs, produces, and globally distributes a proprietary metal-to-metal press connection system for high-pressure and high-temperature piping. The core technology joins steel and stainless-steel pipes without welding and without elastomeric seals, using specially developed press tools (offered in four sizes with matched inserts and accessories) to create a permanent, leak-tight connection in roughly a minute. The product portfolio spans a standard catalogue of fittings (straight, repair, reduction, threaded, end cap, DKO, tee, elbow, distributors, bended pipe, and SAE/DIN/ANSI flanges), customer-specific CNC-machined specials, the HAELOK THERMO line dedicated to district heating, and the press tooling required for installation.

The company sells exclusively to enterprise B2B customers across oil and gas, district heating and municipal utilities, fire protection for high-rise and maritime applications, mechanical and plant engineering, refrigeration, and transport technology. Go-to-market is sales-led, combining direct shipment of catalogue items from a German warehouse with an international network of HAELOK-branded sales partners. Supporting revenue streams include custom manufacturing, tool repair, and certified installer training. Pricing is not publicly disclosed.

HAELOK monetizes through hardware sales of fittings and tools, custom CNC production runs, repair services, and training. Its competitive position rests on an unusually dense stack of safety-critical certifications — ISO 9001, ASME B31.5, AGFW 449, Bureau Veritas, DNV, DVGW (including H2READY for hydrogen), FFI, IACS P2.11, PED Cat III, and TÜV SÜD gas tightness — which together gate entry into oil and gas, district heating, maritime, and high-pressure firefighting markets. Manufacturing is entirely European, the firm is self-funded with no external investors on record, and revenue is not publicly disclosed.

Core offering

HAELOK AG manufactures proprietary metal-to-metal press connection systems used to join steel and stainless steel pipes without welding and without elastomeric seals. The portfolio includes standard high-performance compression fittings, custom-made fittings, the HAELOK THERMO product line for district heating, and proprietary press tools. Products are designed for extremely high pressures (up to 600 bar), temperatures from -55°C to +400°C, and vibration-intensive environments serving oil & gas, district heating, fire protection, and machinery/plant engineering.

Product overview

HAELOK is a mechanical press connection system manufacturer offering a unified portfolio of metal-to-metal press fittings, flanges, and specialized press tools. The core product line consists of the Standard Range (straight fittings, repair fittings, reductions, threaded fittings, end caps, DKO fittings, union tees, elbows, and distributors) and Custom-Made Products (customer-specific fittings). Supporting products include HAELOK® THERMO (sub-brand for district heating applications), HAELOK® Tools (proprietary press tools in four sizes with inserts and accessories), and flange connections in SAE, DIN, and ANSI/ASME standards. The system uses proprietary press tools to create permanent, leak-tight metal-to-metal connections without welding or elastomeric seals, suitable for extreme pressures, temperatures, and vibration environments across oil & gas, district heating, fire protection, and industrial applications.

Direct peers

• Swagelok: Swagelok is a global leader in high-pressure, high-purity fluid system components including fittings, valves, and hoses. It directly competes with HAELOK in oil & gas, instrumentation, and high-pressure industrial applications.
• Hy-Lok: Hy-Lok manufactures compression and instrument fittings for high-pressure industrial piping. It overlaps directly with HAELOK's metal-to-metal compression fitting technology and serves similar oil & gas, petrochemical, and energy customers.
• Ham-Let Group: Ham-Let is an Israeli-based manufacturer of high-quality fittings, valves, and connectors for industrial, instrumentation, and high-purity applications. Its compression fittings compete with HAELOK's metal-to-metal press system in oil & gas and process industries.
• Viega: Viega is the global category leader in metal press fitting systems for plumbing, heating, and industrial pipe connections. It competes head-on with HAELOK in press-to-connect technology, installer training programs, and proprietary tool ecosystems.
• Geberit: Geberit is a Swiss plumbing and pipe connection specialist with leading market share in press-fit systems across Europe. It is comparable to HAELOK on geography (Swiss HQ), product category (press fittings), and industrial/utility customer base.

Regional players

• Raccorderie Metalliche: Italian manufacturer of press fittings (inOXPRES, steelPRES, copperPRES) and pressing tools. It is directly comparable on product but with strongest presence in southern Europe, making it primarily a regional versus HAELOK's more globally distributed system.
• FRABO: Italian press fitting manufacturer offering compression, push-fit, and press systems for plumbing and heating. Comparable to HAELOK on metal press connection technology, primarily focused on the European market.

Broad incumbents

• Watts Water Technologies: Watts Water Technologies is a US-listed manufacturer of water and plumbing products including fittings, valves, and flow control. It serves district heating, plumbing, and industrial markets that overlap with HAELOK's THERMO and process segments.
• Parker Hannifin: Parker Hannifin is a diversified motion and control technologies leader with a broad fluid handling portfolio including fittings, valves, and instrumentation. It serves many of the same industrial and oil & gas customers as HAELOK but as part of a much larger portfolio.
• Aalberts Industries: Aalberts is a Dutch industrial group whose Hydronic Flow Control and Surface Treatment divisions include pressing technologies and pipe connection systems (e.g., Comap, Henco, VSH). It is comparable as a broader incumbent with overlapping press-fit and connection technology offerings.
