Metric Male to Metric Male Adapters - Stainless Steel

Connect compatible female metric fluid connections with our Metric Male to Metric Male Adapters - Stainless Steel. Available in M10 x 1.00 and M10 x 1.25 thread combinations, each adapter combines a convex male connection with a concave male connection for joining components with the corresponding mating seat geometry.

Why Choose Our Stainless Steel Metric Male to Metric Male Adapters?

Convex to Concave Connection

Combines a convex male connection at one end with a concave male connection at the other for joining compatible female fittings with the corresponding sealing surfaces.
M10 Thread Options

Available in M10 x 1.00 to M10 x 1.00, M10 x 1.00 to M10 x 1.25 and M10 x 1.25 to M10 x 1.25 configurations.
Seat-Sealed Connection

The straight metric threads provide retention while the corresponding convex and concave mating surfaces provide the fluid seal.
303/304 Stainless Steel

Offers excellent strength and durability for demanding automotive and motorsport applications.
Natural Stainless Steel Finish

The corrosion-resistant natural finish requires no additional coating and provides a clean, durable appearance.
Precision CNC Machined in the UK

Manufactured in the United Kingdom for accurate thread form, sealing geometry and consistent fitment.

Check Both Thread Pitch and Seat Geometry

M10 x 1.00 and M10 x 1.25 connections share the same nominal thread diameter but have different thread pitches and are not interchangeable. The mating seat geometry must also be compatible with the convex or concave connection at each end of the adapter.

Adapter Type: Metric Male to Metric Male Adapter Convex to concave connection
Material: 303/304 Stainless Steel Excellent strength and durability
Finish: Natural Stainless Steel Corrosion-resistant
Manufactured In: United Kingdom Precision CNC machined
Reusable: Yes Provided the threads and sealing surfaces remain undamaged

Connection 1: Metric Male - Convex Convex sealing seat
Connection 2: Metric Male - Concave Concave sealing seat
Thread Type: Straight Metric Threads provide retention rather than the fluid seal
Sealing Method: Mating Seat Convex and concave sealing geometry must match the mating connections

Frequently Asked Questions

What are metric male to metric male adapters used for?
They are used to join two compatible female metric fluid connections. These adapters combine a convex male connection at one end with a concave male connection at the other.
What thread sizes are available?
Available configurations include M10 x 1.00 convex to M10 x 1.00 concave, M10 x 1.00 convex to M10 x 1.25 concave and M10 x 1.25 convex to M10 x 1.25 concave.
What is the difference between M10 x 1.00 and M10 x 1.25?
Both have a nominal 10 mm thread diameter, but the thread pitch is different. M10 x 1.00 has a 1.00 mm pitch while M10 x 1.25 has a 1.25 mm pitch, so the two threads are not interchangeable.
What do convex and concave mean?
Convex and concave describe the shape of the sealing seat at each connection. The seat must correspond with the mating fitting for the connection to seal correctly.
Does the metric thread itself create the fluid seal?
No. These are straight metric threads that provide retention. The fluid seal is created between the corresponding mating seat surfaces.
Do these adapters require thread sealant?
No. Thread sealant should not be required because the fluid seal is created at the mating seat rather than on the straight metric thread.
What are the adapters made from?
They are precision CNC machined from 303/304 stainless steel for excellent strength and durability.
Where are these adapters manufactured?
They are precision CNC machined in the United Kingdom.
Are these adapters reusable?
Yes. They can be removed and reused provided the threads and sealing surfaces remain clean and undamaged.
