Hey everyone,

Installing and removing lens ports is one of the most important skills when working with your Salted Line underwater camera housing. In this step-by-step guide, we show you exactly how it’s done, following the official method.

This guide applies to Salted Line waterproof A7SIII, A7III/A7RIII, A7IV(GEN 1), A1 housings, and other supported models.

 

What You’ll Learn

• How to correctly remove the dust caps
• How to handle the O-ring
• How to apply original Silicone grease
• How to install ports with locking tooth and without locking tooth (including lock pin)
• How to safely remove the lens port

Step-by-Step Installation

1. Remove the dust caps

Take off the dust cap from the front of the Salted Line underwater camera housing and from the lens port.

2. Remove the O-ring (if necessary)

Carefully pull the large O-ring out of the groove on the lens port only if it is dirty and needs to be cleaned. Avoid stretching it.

3. Clean the O-ring

Wipe the O-ring thoroughly with a paper tissue.

4. Apply silicone grease

Apply a small, even amount of original Silicone grease to the O-ring.

5. Reinstall the O-ring

Place the greased O-ring back into the groove.

Now install the port - there are two types:

A. Port with locking tooth

• Align the locking tooth on the port with the corresponding notch on the housing.

• Push the port straight and firmly into the housing.

• Rotate the port clockwise until it is fully secured and the tooth locks in place.

B. Port without locking tooth

• Align the port with the alignment mark on the housing body.

• Push the port straight and firmly into the housing. 

• Rotate the port clockwise until it is fully seated.

• Secure the port with the lock pin: insert the lock pin into the designated hole and tighten it with the provided screwdriver.

Step-by-Step Removal

1. If a lock pin was used - first remove it with the screwdriver.

2. Press and hold the release button on the side of the housing (not required for ports secured with lock pin).

3. Rotate counterclockwise until the port releases.

4. Pull the port straight out.

5. Put the dust caps back on both the housing and the lens port to keep everything clean.
