trying to hook 12mm L series tube up to a G 3/8 BSPP port, is this the right adapter?
Answer by: Customer Support on Feb 15, 2026, 6:53 AM
For that exact connection, yes. It is a steel metric flareless tube fitting that mates 12.00 mm L Series tubing on one side to a G 3/8 male BSPP thread on the other, and it includes a seal to help keep the joint leak-free.

got a 12mm L Series line running to a BSPP port on a manifold block, this fitting handle that transition without needing an adapter in between?
Answer by: Customer Support on Mar 18, 2026, 6:40 AM
That's exactly what it's built for. The C1KW79 connects 12mm L Series flareless tubing directly to a G 3/8 Male BSPP thread, so no intermediate adapter is needed. The built-in seal handles the thread-end connection, keeping the joint leak-free without extra hardware in the line.
