Fully interchangeable with *Grayloc® connectors

The Metalok360 M-LOK clamp connector is an equal alternative to *Grayloc® or other clamp connector manufacturers’ products.

The Metalok360 M-LOK clamp connector is designed to offer the strength and sealing technology of a welded joint and versatility of a mechanical joint. It serves the same purpose as a bolted flange assembly, with added advantages of being more easily installed (only 4 bolts) and up to 75 percent lighter and smaller by comparison to ANSI or API flanges.

The connector consists of 2 hubs, 1 seal ring, 1 clamp set with 4 bolts and 8 nuts.

All materials available

M-LOK connectors have applications in a wide range of industries:

Aerospace manufacturing
Chemical processing
Coal gasification and liquefaction
Environmental
Food & beverage processing
Fossil and nuclear power generation
Industrial gas manufacturing
Marine & ship building & maintenance
Oil and gas offshore & onshore production
Petroleum refining
Pulp & Paper
Synthetic fuels processing

M-Lok’s connection systems provide solutions to chronic problems associated with standard ANSI and API flange connections.

Leak-Free Reliability
Our reusable metal-to-metal seal ring offers leak-free with zero leakage reliability over traditional ANSI and API gaskets. Our seal rings offer welded joint integrity and can be used in critical and chronic leak areas. M-LOK is an easy-to-assemble, engineered as a high-performance alternative to flanges.

Weight Savings
With weight savings of up to 75% in comparison to ANSI flanges, our connection systems can typically save up to 1 million lbs. of weight on an offshore floating platform.platform. an offshore floating platform.

Space Savings
Space savings of up to 50% with smaller O.D. and length dimensions compared to ANSI/API flanges. Pipe runs are closer together for more room for process equipment and future tie-backs. Ideal for small O.D. pull-in-head requirements.

External Loads
Our connectors are able to handle high fatigue and high bending moments. We can optimize the design of the connector as needed to meet project requirements.

Quick Assembly
Our connection systems typically use less and smaller bolts in comparison to ANSI or API flanges. Our catalog of connectors include clamps that only require four bolts and connectors that are self aligning.

Cost Savings
In many cases, our connector assemblies are less expensive to purchase than the corresponding ANSI or API flange assembly. Our leak-free seal rings save operational costs.

High Pressure/Temperature
Our connector systems have applications in high pressure and/or high temperature where they outperform ANSI and API flanges in terms of reliability and leak free service.

8-in. – 1500# ANSI Class Comparison just 4 bolts to install, compared with 8-24 bolts for conventional flanges. M-LOK connector is substantially smaller in size and 75% lighter in weight when compared to an equivalent ANSI or API flange class.

M-LOK Clamp Connector vs. ANSI/API Flanges Advantages of M-LOK Clamp Connector

Self energized and pressure enhanced seal
Seal ring is designed to be reusable
Small relative movements between hubs can be accommodated by seal ring deflection
Clamp assembly lighter and requires less space
Clamp bolts are oriented perpendicular to pressure end thrust and are not subjected to hydrostatic loading due to pressure
Small outside dimensions allow use in more confined and congested areas
Clamps can be conveniently rotated for desired bolt orientation
Four bolt design has built in safety factor which allows for bolt failure without loss of sealing integrity
The connectors method of sealing does not require precision bolt loading, thus easier

Disadvantages of ANSI/API Flanges

Larger and bulkier flange forging
Often more and larger bolts
Generally a crush type gasket
High bolt torque required to seat and maintain contact pressure
Costly and timely hydraulic tensioning equipment
Poor adaptability to changing conditions (temperature)

Even make-up required to avoid impingement of gasket
Gasket is not reusable
Gasket has to handle piping bending loads
Performance not good in high vibration
ANSI Flange design is over 100 years old and outdated technology

M-Lok Clamp Assembly

Our M-LOK Clamps are manufactured as interchangeable segments and sold as a set with bolting included. Standard clamp materials are carbon steel (AISI 4130/4140) or stainless steel (ASTM A182 F304). Other materials are available on request.

Bolting: Two studs are used in each ear of the clamp to provide redundancy in bolting strength. Bolting is provided with UNC/8UN thread series with spherical-faced heavy hex nuts. Bolt coating can be supplied based on customer requirements.
