GI M/F Bend in Kenya | Sparks Plumbing Experts

A GI M/F bend turns a galvanized pipe run with a smooth curve. It has a male thread at one end and a female thread at the other.

As a result, it screws straight into a tee, socket or valve without a nipple. The gentle curve also keeps flow loss low.

What is a GI M/F bend?

A GI M/F bend is a galvanized fitting with a male thread on one end and a female thread on the other, shaped as a smooth bend. It changes the direction of a pipe run.

Because one end is male, it screws straight into another fitting without a nipple. In addition, the larger radius of a bend causes less flow loss than a sharp elbow.

Key terms explained

Galvanized iron (GI): Iron or steel coated with a layer of zinc. The zinc corrodes first, so it protects the metal underneath from rust.
BSP thread: British Standard Pipe thread, the common pipe thread in Kenya. Tapered BSP threads (BSPT, ISO 7-1) tighten into a seal as you screw them together.
Nominal size: The trade size of a pipe or fitting, such as 1/2 inch. It names the pipe size, so it is not an exact measurement of the outside diameter.
Thread sealant: PTFE tape, hemp with jointing paste, or an anaerobic sealant applied to male threads. It fills tiny gaps so the joint does not leak.
M/F: Male/female: one external thread and one internal thread.
Bend radius: How gradually a bend turns. A larger radius gives smoother flow.

Frequently asked questions

What does M/F mean on a GI bend?

It means one male (external) thread and one female (internal) thread.

Can I order GI M/F bends in bulk?

Yes. Include sizes and quantities in your quote request.

Do you deliver GI M/F bends outside Nairobi?

Yes. We supply customers across Kenya, and we also serve buyers in Uganda and Tanzania. Delivery or courier arrangements are agreed when you confirm the order.

How much does a GI M/F bend cost in Kenya?

The price depends on the size, the quantity and current steel prices. Therefore, send your list with a quote request and we will reply with current figures.

Should I use PTFE tape or paste on GI M/F bends?

Either works when applied correctly. Wrap PTFE tape clockwise on the male thread, or use hemp with jointing paste on larger sizes. Do not over-tighten, because that can crack the fitting.

Can GI M/F bends connect to copper pipe?

Avoid a direct joint between galvanized steel and copper, because the zinc then corrodes quickly. Instead, use a brass adaptor or, better, a dielectric union as the transition.
