Multiflex K7 Aluminium Eye End For 33C Control Cables

The Multiflex K7 / LM-K-7 Metal Eye End is an aluminium cable-end fitting for compatible EC-033, EC-133 and universal 33C / 3300 engine control cables. Its 10-32 UNF female thread screws onto the cable’s moving threaded rod, while the single circular eye provides a pinned connection to a throttle, gear-shift, gearbox or other compatible operating linkage.

Unlike a forked clevis, the K7 does not straddle the operating lever. The eye is positioned inside a suitable forked bracket or alongside a compatible linkage and secured with an installation-specific pin or bolt.

What Is the Multiflex K7 Used For?

The K7 forms the pinned connection between the moving threaded rod of a mechanical control cable and the lever or linkage operated by that cable.

It can form part of a correctly specified:

• Gear-shift control installation
• Throttle-control installation
• Inboard engine control system
• Outboard engine control system
• Sterndrive control installation
• Gearbox selector connection
• Choke or engine-stop control using a compatible cable
• Replacement EC-033 cable installation
• Replacement EC-133 cable installation
• Compatible universal 33C / 3300 cable installation
• Industrial push-pull control linkage

When the remote control is operated, the inner cable rod pushes or pulls the K7. A separate pin or bolt through the eye transfers this movement to the connected operating lever while allowing the joint to pivot through its working arc.

What Is Included?

• 1 x Multiflex K7 / LM-K-7 metal eye-end fitting

The available Multiflex product information does not identify a pin, bolt, washer, spacer, locknut or retaining clip as part of the K7 supply.

Not included unless expressly stated:

• Multiflex EC-033 control cable
• Multiflex EC-133 control cable
• Remote control lever or control box
• Engine throttle lever
• Gearbox selector lever
• Linkage pin or mounting bolt
• Pin retaining clip
• Retaining nut
• Washers or spacers
• Cable outer-casing clamp
• Structural support bracket

• Cable-end pivot
• A second eye end
• Other engine-specific linkage fittings

Which Control Cables Are Compatible?

• Multiflex EC-033
• Multiflex EC-133
• Compatible universal 3300 / 33C control cables

The selected cable must have a compatible 10-32 UNF male threaded moving end. Cross-brand compatibility also depends on the eye diameter, fixing pin, linkage geometry, operating load and available articulation.

Is the Multiflex EC-133R Compatible?

A specialist Multiflex distributor lists EC-133R compatibility, but the current official Multiflex K7 product information lists only EC-033 and EC-133. Confirm EC-133R fit before publication or installation.

Is the Multiflex EEC-133 Edge Cable Compatible?

The current official K7 product data do not specifically list the EEC-133 Edge cable.

Although EEC-133 uses a universal 10-32 UNF threaded end, compatibility should be confirmed from the complete linkage geometry and operating requirements before installation.

Is the K7 Suitable for Universal 33C / 3300 Control Cables?

Yes. The officially compatible EC-033 and EC-133 cables are universal 3300-series cables commonly described as 33C control cables.

Before fitting another manufacturer’s cable, confirm:

• 10-32 UNF male cable-end thread
• Eye-terminal geometry
• Operating-lever or bracket arrangement
• Linkage pin or bolt diameter
• Required articulation
• Cable travel
• Operating load
• Available installation clearance

A matching cable-end thread alone does not guarantee complete compatibility.

How Does the K7 Eye End Work?

1. Screw the K7 onto the control cable’s 10-32 UNF moving rod.
2. Position the eye within a compatible forked bracket or alongside the operating linkage.
3. Align the K7 eye with the linkage mounting hole.
4. Insert a correctly sized pin or bolt through the connection.
5. Secure the pin or bolt using the specified retaining component.
6. Adjust the cable to the correct neutral, idle or rest position.
7. Operate the control through its complete range and confirm free movement.

What Thread Does the K7 Use?

• Female thread: 10-32 UNF
• Alternative description: 3/16in UNF

The female thread screws onto the male moving rod of a compatible control cable. No installation torque or minimum thread-engagement figure is published for the K7.

What Is the K7 Eye Diameter?

Multiflex does not publish the K7 eye diameter.

Do not assume that the K7 accepts a 6mm, 6.4mm, 7.9mm, 8mm or another standard fixing size. Measure the physical K7 and intended linkage pin before installation.

What Pin or Bolt Is Required?

The required pin or bolt depends on:

• The actual K7 eye diameter
• Operating-lever or bracket thickness
• Linkage-hole diameter
• Required articulation
• Available side clearance
• Operating load
• Retaining method

No fixing-pin or bolt specification is published for the K7. Use a correctly sized corrosion-resistant linkage fastener with a positive retaining method.

Does the K7 Secure the Cable Outer Casing?

No. The K7 attaches to the moving threaded cable rod.

The stationary cable outer casing must be secured separately using:

• Multiflex K3 control cable clamp
• A remote-control-box retaining arrangement
• An engine-side mounting bracket
• Another approved control cable support

How Does the K7 Differ From the Multiflex K5?

Multiflex K7

How Does the K7 Differ From the Multiflex K8?

• K7: Metal eye end, supplier-described as aluminium
• K8: Plastic eye end

No official dimensional or maximum-load comparison is published between the K7 and K8.

Which Cross-Brand Eye Terminal Is Comparable?

The closest documented cross-brand terminal-eye fitting is the SeaStar / Teleflex 317413 / HA518.

• Thread: 10-32 UNF
• Published eye diameter: 5/16in
• Published competitor dimensions: 34 x 19 x 9.5mm

These are competitor specifications and must not be assigned to the Multiflex K7 without physical verification.

Is There an Ultraflex Equivalent?

No identical Ultraflex metal eye-terminal model was verified in the current product information reviewed for this listing.

The Ultraflex L25 uses the same general 10-32 UNF cable format but is a forked clevis with a 7.1mm jaw and 6.4mm pin. It is not a direct geometric equivalent to the K7.

Is the K7 Aluminium?

The official Multiflex page describes the K7 as a metal eye end. A specialist Multiflex distributor identifies the material as aluminium.

The aluminium alloy, surface treatment and formal corrosion-test specification are not published.

What Are the K7 Dimensions?

Multiflex does not publish the following K7 dimensions:

• Overall length
• Overall width
• Overall thickness
• Eye outside diameter
• Eye inside diameter
• Threaded-hole depth
• Distance from cable end to eye centre
• Maximum linkage thickness
• Maximum articulation angle
• Product weight

Does the K7 Hold One or Two Control Cables?

The K7 connects one control cable to one operating linkage. Separate shift and throttle cables may require one eye end for each mechanism.

Is the Operating Lever or Mounting Pin Included?

No operating lever is included. A mounting pin or bolt is not identified as part of the K7 supply.

Can the K7 Be Used with Steering Cables?

No. The K7 is intended for mechanical engine and industrial control cables, including compatible shift, throttle and other push-pull controls.

It is not intended for rotary steering cables, rack-and-pinion steering cables, hydraulic steering hoses or steering link arms.

Is a Maximum Working Load Published?

No maximum working load or proof load is stated. Select the K7 according to the control cable, operating linkage, engine or gearbox requirements and complete connection geometry.
