Ultraflex L12 Brass Cable End Pivot Pin For 33C Control Cables

The Ultraflex L12 / 4-L12 Control Cable-End Pivot is a brass linkage fitting for compatible C2, C8, MACHZero and universal 33C / 3300 engine control cables. It screws onto the cable’s 10-32 UNF threaded moving end and uses a removable pivot pin to connect the cable to a throttle, gearbox or other operating lever up to 6mm thick.

The pivot allows the cable end to articulate as the operating lever moves, helping maintain alignment through the cable’s push-pull stroke.

What Is the Ultraflex L12 Used For?

The L12 forms the articulated connection between the moving threaded end of a mechanical engine control cable and the lever operated by that cable.

It can be used in 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

• Compatible universal 33C cable installation

What Is Included?

• 1 x brass cable-end pivot
• 1 x removable pivot pin
• 1 x split pin / cotter pin
• 2 x pivot washers

The L12 is sold as one cable-end fitting.

Not included unless expressly stated:

• Ultraflex C2 control cable
• Ultraflex C8 control cable
• Ultraflex MACHZero control cable
• Remote control lever or control box
• Engine throttle lever
• Gearbox selector lever
• Cable outer-casing clamp
• Structural support bracket
• Cable locknut
• Clevis
• Ball joint
• A second cable pivot
• Other engine-specific linkage fittings

Which Control Cables Are Compatible?

• Ultraflex C2
• Ultraflex C8
• Ultraflex MACHZero
• Compatible universal 3300 / 33C cables

Specialist suppliers also list compatible 33C cable families from Morse, Teleflex, SeaStar, Dometic and Multiflex. Cross-brand fitment must be confirmed from the cable thread, pivot dimensions and operating-lever geometry.

Is the L12 Suitable for 33C / 3300 Control Cables?

Yes. The L12 is designed for compatible universal 330 / 3300 / 33C-series control cables.

Before ordering, confirm:

• Cable manufacturer and model
• 10-32 UNF male cable-end thread
• Pivot-pin diameter
• Operating-lever hole diameter
• Lever thickness
• Required articulation
• Cable travel
• Operating load
• Available installation clearance

How Does the L12 Pivot Work?

1. Screw the brass L12 body onto the cable’s 10-32 UNF threaded moving rod.
2. Position the first washer as required by the linkage arrangement.
3. Pass the pivot pin through the operating lever.
4. Fit the remaining washer where required.
5. Secure the pin using the supplied split pin.
6. Adjust the cable to the correct neutral, idle or rest position.
7. Check that the pivot articulates freely throughout the lever’s movement.

What Does the 6mm Lever Thickness Mean?

The L12 is intended for an operating lever with a maximum thickness of approximately:

• 6mm
• 0.24in

The pivot pin must pass fully through the lever while leaving sufficient space for the washers and split pin to be installed correctly.

The separate Ultraflex L121 is intended for an approximately 3mm lever arrangement.

What Thread Does the L12 Use?

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

The female thread screws onto the male threaded rod end used by compatible C2, C8, MACHZero and other 33C-style control cables.

Does the L12 Secure the Cable Outer Casing?

No. The L12 connects the moving cable rod to an operating lever.

The stationary cable outer casing must be secured separately using:

• Ultraflex L14 saddle clamp
• A remote-control-box retaining arrangement
• An engine-side support bracket
• Another approved control cable clamp

Is the L12 the Ultraflex Equivalent of the Multiflex K10?

The L12 is the closest Ultraflex functional counterpart to the Multiflex K10.

Ultraflex L12

• Brass construction
• Maximum lever thickness of 6mm
• Supplied with a split pin and two washers
• Listed for C2, C8 and MACHZero
• Part number 30334F

Multiflex K10

• Stainless-steel construction
• Officially listed for EC-033 and EC-133
• Supplier-published dimensional drawing
• Part reference LM-K-10

The products perform the same general function but should not be treated as guaranteed dimensional replacements.

How Does the L12 Differ From the L121?

Ultraflex L12 / 4-L12

• Maximum lever thickness: 6mm
• Brass construction
• 10-32 UNF / 3/16in thread
• Supplied with split pin and two washers
• Part number 30334F

Ultraflex L121 / 4-L121

• Intended for an approximately 3mm lever
• Brass construction
• 10-32 UNF thread
• Separate product reference

What Are the L12 Dimensions?

• Maximum lever thickness: 6mm
• Supplier-published outer dimensions: Approximately 15.9 x 11mm
• Supplier-published inner or pin-related diameter: Approximately 6.3mm

The overall pivot length, full pin length, washer thickness, split-pin diameter and maximum articulation angle are not consistently published. Check the physical product where exact dimensions are critical.

What Lever Hole Is Required?

The operating lever must have a hole that accepts the L12 pin without binding or excessive clearance and leaves sufficient material around the hole for the operating load.

Check the physical pivot and lever before drilling or modifying the linkage.

Does the L12 Hold One or Two Control Cables?

The L12 connects one control cable to one operating lever. Separate shift and throttle cables may require one pivot for each mechanism.

Is the Control Lever Included?

No. The L12 is the cable-end pivot fitting only. The control cable, operating lever and cable-support components are supplied separately.

Is the L12 Brass?

Yes. The L12 is manufactured from brass.

The brass alloy, surface coating and formal corrosion-test specification are not published.

Can the L12 Be Used with Steering Cables?

No. The L12 is intended for mechanical engine control cables, including compatible shift and throttle cables.

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

Is a Maximum Load Published?

No maximum working load or proof load is stated. Select the L12 according to the control cable, operating lever, engine or gearbox requirements and complete linkage geometry.

• Confirm that the operating lever is no more than 6mm thick
• Check the lever-hole diameter against the physical pivot pin
• Inspect the cable rod thread for damage
• Start the pivot body on the cable thread by hand
• Do not cross-thread the brass pivot
• Maintain sufficient cable-thread engagement
• Position the washers correctly
• Insert the pivot pin fully through the operating lever
• Install the split pin completely
• Ensure the pivot moves freely
• Align the control cable to avoid side loading
• Secure the cable outer casing separately
• Maintain the cable manufacturer’s minimum bend radius
• Operate the control through its complete range
• Confirm positive forward, neutral and reverse positions where used for shifting
• Confirm that the throttle returns fully to idle
• Check that the cable rod does not bottom out or overtravel
• Inspect the pivot, pin, washers and split pin regularly
• Replace worn, bent, loose or damaged components
• Do not operate the control system if the pivot binds

Engine shift and throttle controls are safety-critical systems. Installation should be completed according to the current Ultraflex, engine, gearbox and remote-control instructions by a competent marine technician.
