Product Description

OTS Guardian M16 Equalizing Wire Form Screw Stainless Steel

The OTS Guardian Equalizing Wire Form Screw (M16 Stainless Steel Screw, SKU: 244018-000 / DIR-244018-000) is an essential OEM replacement hardware piece designed specifically for the Ocean Technology Systems (OTS) Guardian Full Face Mask (FFM) equalizing assembly.

This screw holds the inner wire form and equalizing nose-block pad securely in place through the main port of the mask visor, allowing divers to adjust the height and angle of the nose pad to clear their ears effortlessly during descent.

The Guardian Full Face Mask utilizes an internal equalization assembly that allows divers to block their nostrils and equalize middle-ear pressure while underwater. The M16 screw secures the wire-form mechanism necessary for this operation. Proper installation helps keep the equalizing assembly correctly aligned and functioning smoothly.

The OTS Guardian M16 Equalizing Wire Form Screw (Part Number 244018-000) is a genuine replacement fastener used within the equalizing mechanism of the **OTS Guardian Full Face Mask (FFM). The screw secures the Equalizing Wire Form assembly to the Equalizer Base, ensuring reliable operation of the mask's nose-block equalization system.

Listed as M16 in the official Guardian maintenance schematic, the screw works in conjunction with the Wire Form, Equalizing Block (Part #875003-000) and associated equalizing components to allow divers to pinch their nose for pressure equalization while maintaining the seal and functionality of the full-face mask. 

As a critical component of the Guardian's equalizing assembly, replacing a lost, damaged, or corroded screw helps ensure proper movement and secure retention of the equalizing mechanism during diving operations.

  • Genuine OTS OEM replacement part.
  • Specifically designed for the OTS Guardian Full Face Mask.
  • Designated as Item M16 in Guardian schematics.
  • Secures the Equalizing Wire Form assembly.
  • Helps maintain proper equalizer operation.

TECH SPECS:

PART NUMBER = OTS-244018-000

THREAD SIZE / TYPE = M16 Machine Thread

MATERIAL - Marine-Grade Passivated Stainless Steel / Polymer

APPLICATION POINT - External visor port housing connecting to the internal wire form

CORROSION RESISTANCE - Saltwater passivated to prevent galling and oxidation

Product Type: OEM Replacement M16 Threaded Retention Screw / Fastener

Compatibility: Exclusively designed for the OTS Guardian Full Face Mask equalizing assembly. (Does not fit Spectrum, Interspiro Divator, or Ocean Reef IDM systems).

Primary Function: Anchors the internal metal wire form and silicone nose block assembly to the mask frame, maintaining a rigid pivot point so the diver can press the outside of the mask to seal their nostrils for Valsalva equalization.

Operational Function

  • Precision Height Adjustment: The screw works in tandem with the internal wire form bracket and base pads (included in OTS sizing kits), allowing divers to move the nose pad up or down to fit various nose bridge lengths.

  • Leak-Free Retention: Features a precise shoulder rim that compresses the internal O-ring seal against the visor shell, ensuring gas and water stay separated while maintaining mechanical tension.

  • Corrosion-Proof Construction: Built to withstand constant exposure to saltwater and high internal humidity from heavy breathing inside the full face mask.

Tips & Tricks for Installation & Maintenance

Dialing in Your Nose Block Height

  • Before tightening the M16 screw completely, perform a dry fit with your suit and hood on.

  • Slide the wire form up or down so that when you push the mask skirt upward from the outside, the silicone nose pads firmly block your nostrils without pinching your upper lip.

Hand-Tighten First (Avoid Over-Torquing)

  • Thread the screw into the visor port by hand to ensure the M16 threads start smoothly without cross-threading into the polymer housing.

  • Use the proper-sized driver or hex key to snug the screw down until firm. Do not over-torque, as excessive pressure can crack the polycarbonate visor surrounding the mounting hole.

Inspecting the Sealing O-Ring

  • Whenever you remove or loosen the equalizing wire from the screw, inspect the small rubber O-ring underneath the screw shoulder for cracks, sand grit, or flattened spots. Replace the O-ring if it shows wear to prevent slow micro-leaks into the mask.

Post-Dive Rinsing

  • Soak the nose-block area in fresh water after diving. Trapped salt crystals inside the wire form screw threads can bind over time, making future height adjustments difficult.
