SAE, Metric, or Specialty Kit Type

This is a specialty scuba service O-Ring kit made for K-valves and related scuba equipment.

It is designed for common scuba service points, including:

• K-valves
• Yoke regulator connections
• DIN regulator valve connections
• LP hose connections
• HP hose and SPG swivel connections
• Tank valve bonnet nuts
• Tank neck sealing locations

This kit is not a general shop assortment. It is built for scuba service work where having the right common O-Ring ready can help keep repairs moving.

Material Compatibility

The O-Rings in this kit are made from Buna-N, also known as Nitrile or NBR.

Buna-N is a common general-purpose sealing material used for oil resistance, abrasion resistance, and durable sealing in many shop and equipment applications. In this kit, the Buna-N O-Rings are intended for compressed air scuba systems only.

Operating temperature:

• -40°F to +225°F
• -40°C to +107°C

Important compatibility note:

• For compressed air scuba systems only
• Not intended for oxygen-enriched service unless the material, cleaning, lubricant, and service requirements are confirmed by a qualified scuba equipment technician
• Do not use for unknown chemicals or fluids
• Confirm compatibility for any critical or regulated service application

Durometer and Seal Performance

This kit uses Buna-N O-Rings selected for practical scuba service sealing needs.

Durometer means the hardness of the rubber. Hardness matters because it affects how the O-Ring seals, how it handles pressure, and how well it resists damage during use.

For scuba service work, the correct material, correct hardness, correct size, and correct installation all matter. A seal that is close but wrong can leak, wear early, or fail during service.

Best Uses

This scuba O-Ring kit is best used by:

• Dive shops
• Scuba service centers
• Regulator repair technicians
• Tank valve service technicians
• Commercial dive support teams
• Scuba equipment rental departments
• Field repair kits for qualified service professionals
• Resellers needing a made-to-order scuba O-Ring assortment

This kit is not ideal for unknown chemicals, oxygen-enriched systems, critical aerospace, medical, or highly specified applications unless the required material, cleaning process, certification, and traceability are confirmed before use.

Quality and Reliability

The OSK™ Scuba Tank K Valve Master O-Ring Kit is built as a professional repair and maintenance solution, not a cheap filler assortment.

Customers benefit from:

• Known Buna-N material
• Useful scuba service size selection
• Practical quantities per size
• Reliable replacement O-Rings
• Made-to-order kitting
• Support from The O-Ring Store LLC
• ISO9001:2015 certified quality system

A better O-Ring kit helps reduce wrong-size repairs, wasted time, and repeat service issues. For dive shops and repair professionals, that means a cleaner bench, faster service, and more confidence during common scuba equipment repairs.

Organized Storage Case

This kit is organized to help technicians find the right O-Ring faster during service work.

The size selection is grouped by common scuba use, making it easier to match the O-Ring to the repair point. This helps reduce mistakes and keeps the repair process moving, especially when a customer is waiting or a service bench has multiple jobs in progress.

Piece Count and Refill Value

This kit includes 300 total O-Rings across 11 common scuba service sizes.

The value is not only the total piece count. The real value is having useful scuba repair sizes in practical quantities.

When common sizes run low, customers can reorder replacement O-Rings from The O-Ring Store LLC instead of replacing the entire kit. This helps keep the kit working longer and supports repeat service needs.

This made-to-order scuba O-Ring kit is a smart service tool for shops that want to reduce downtime and keep common scuba repair O-Rings ready.

For a dive shop or repair center, one missing O-Ring can slow down a service job. Having the correct common sizes on hand helps prevent delays, reduces trips to the parts counter, and keeps repair work moving.

The value is not just the O-Rings. The value is faster service, better organization, fewer delays, and easier refills.

Before You Buy

Before ordering, confirm that this kit matches your service needs.

Check the following:

• Match the O-Ring size to the original O-Ring or sealing gland
• Match the material to the gas, temperature, pressure, and environment
• Do not assume all rubber materials work in every scuba system
• Confirm service requirements for oxygen-enriched systems before use
• For critical applications, confirm required material, hardness, certification, cleaning, and traceability before installation

This kit is made for compressed air scuba systems only.
