What Is Type K (OXY) Copper Tube?
Type K (OXY) copper tube combines the heavy wall thickness of Type K copper with special cleaning and end protection intended for controlled gas-distribution systems. It is commonly specified where ordinary plumbing copper does not provide the required level of internal cleanliness.
The tubing is supplied hard drawn in rigid 20-foot straight lengths. After cleaning and dehydration, the ends are capped to help preserve the internal condition during shipping, storage, and jobsite handling.
Why Cleaned & Capped Copper Matters
Oxygen and medical-gas piping systems require careful control of oils, grease, hydrocarbons, moisture, dust, scale, metal particles, and other contaminants. These materials can create unacceptable cleanliness conditions and may interfere with the safe operation of a completed gas-distribution system.
Factory cleaning, dehydration, and capped ends help protect the tubing before installation. Keep the tube capped until immediately before it is cut, prepared, or joined.
OXY Copper vs. Standard Plumbing Copper
Type K (OXY) Copper Tube
- Prepared for oxygen and controlled gas service
- Internally cleaned and dehydrated
- Factory capped for protected handling
- Manufactured to applicable ASTM B819 requirements
- Selected where project cleanliness requirements are critical
Standard Type K Plumbing Copper
- Designed primarily for water, plumbing, mechanical, and approved utility service
- Typically manufactured to ASTM B88
- Not necessarily supplied with oxygen-service cleaning
- May not have capped ends for controlled internal cleanliness
- Should not be substituted where ASTM B819 or medical-gas cleaning is required
Why Choose Type K Wall Construction?
Heavy-Wall Strength
- Thickest wall among commonly used Type K, L, and M copper tube
- Provides excellent mechanical durability
- Suitable for demanding piping applications when properly specified
- Long service life when properly installed and protected
20-Foot Straight Lengths
- Useful for long controlled gas-distribution runs
- Reduces the number of intermediate joints
- Well suited for hospitals, laboratories, and larger facilities
- Provides rigid, aligned piping in mechanical spaces and corridors
Common Applications
Medical & Healthcare Gas Systems
- Medical oxygen distribution
- Medical air systems
- Vacuum and gas piping where specified
- Healthcare facilities
- Hospitals and surgical centers
- Dental and clinical facilities
Laboratory & Specialty Gas Systems
- Laboratory gas distribution
- High-purity gas systems
- Research facilities
- Industrial specialty gas piping
- Controlled process-gas installations
- Other applications specifying cleaned copper tube
Joining Type K (OXY) Copper Tube
Joining procedures for oxygen and medical-gas piping must comply with the applicable project specification, installation standard, code, and authority having jurisdiction. Maintaining cleanliness throughout cutting, preparation, brazing, purging, and assembly is critical.
- Brazed joints: commonly used for medical-gas and oxygen-service copper piping.
- Nitrogen purge: typically used during brazing to help minimize internal oxidation and scale.
- Clean tools and fittings: use equipment and components suitable for the required cleanliness level.
- Controlled handling: protect all open tube ends throughout the installation process.
- Other joining methods: use only when specifically permitted by the applicable code, specification, fitting manufacturer, and system requirements.
Installation Guidance
- Confirm the required nominal tube size before ordering.
- Verify that ASTM B819 Type K tubing is required for the intended application.
- Keep factory caps installed until immediately before installation.
- Inspect caps and tubing for damage before removing protective seals.
- Do not use tubing if the internal surface appears contaminated.
- Handle tubing with clean gloves and approved tools when required.
- Cut tubing square using clean equipment appropriate for medical-gas or oxygen-service work.
- Remove burrs carefully without introducing debris into the tube.
- Protect open ends whenever installation is interrupted.
- Use approved cleaned fittings and compatible brazing materials.
- Use the required purge-gas procedure during brazing.
- Support piping according to applicable code and engineering requirements.
- Complete required pressure testing, purging, verification, inspection, and certification before placing the system into service.
- Installation should be performed by qualified personnel trained for the applicable gas-piping system.

Frequently Asked Questions
What does OXY copper tube mean?
OXY copper tube refers to copper tubing specially cleaned and protected for oxygen, medical-gas, high-purity, and other controlled gas applications where internal cleanliness is critical.
What standard does this tube meet?
This product is specified to applicable ASTM B819 requirements for seamless copper tube used in medical-gas systems.
What is the difference between ASTM B819 and ASTM B88?
ASTM B819 applies to copper tube intended for medical-gas systems and includes cleanliness-related requirements. ASTM B88 applies to standard seamless copper water tube.
Why is this tubing cleaned?
The tubing is cleaned to remove contaminants such as oils, grease, hydrocarbons, dirt, and other materials that may be unacceptable in oxygen and medical-gas systems.
Why are the tube ends capped?
The caps help preserve the internal cleanliness of the tube during shipping, storage, and jobsite handling.
When should the protective caps be removed?
Keep the tubing capped until immediately before cutting, preparing, or joining the tube.
Is this Type K copper?
Yes. This product uses Type K wall construction, providing the heaviest wall among commonly used Type K, L, and M copper tube classifications.
How long is each piece?
Each piece in this product family is supplied as one rigid 20-foot straight length.
Is this product sold by the foot?
No. This product is sold as a complete 20-foot stick. The displayed price applies to the selected 20-foot length.
Can this tube be used for medical oxygen?
It is intended for approved medical-gas and oxygen-service applications when the tube, fittings, installation procedures, testing, and certification meet the applicable project and code requirements.
Can it be used for other medical gases?
It may be used in approved medical-gas systems where ASTM B819 Type K copper tube is specified. Confirm the exact service and applicable requirements before installation.
Can this copper be brazed?
Yes. Brazing is commonly used for medical-gas and oxygen-service copper piping when completed using approved fittings, brazing alloys, purge procedures, and applicable installation standards.
Should nitrogen be used during brazing?
A nitrogen purge is commonly required during brazing to help reduce internal oxidation and scale. Follow the applicable medical-gas installation standard and project requirements.
Can standard copper fittings be used?
Use fittings that meet the applicable medical-gas or oxygen-service cleanliness and installation requirements. Standard uncleaned fittings should not be substituted when cleaned components are required.
Can this tubing be used for ordinary plumbing?
Although Type K wall construction is suitable for many plumbing applications, this product is specifically prepared and priced for controlled gas service. Standard Type K water tube is usually more appropriate when oxygen-service cleaning is not required.
Why use a 20-foot length?
Twenty-foot lengths allow longer continuous piping runs with fewer joints, which can be beneficial in hospitals, laboratories, healthcare facilities, and other large controlled gas-distribution systems.
