Equal coupling galvanized cast iron

Galvanized cast iron female/female equal coupling plumbing fitting

This galvanized cast iron female/female equal coupling allows threaded fittings or threaded pipes of the same size to be easily connected by screwing; it is particularly useful for joining two pipes together and thus extending their lengths. It is compatible with all galvanized cast iron fittings or black ones, and with threaded galvanized steel pipes or black ones of the same size sold in our online shop. The parts simply screw together, without welding, to make strong assemblies easily.

Description of the female/female galvanized equal coupling:

The equal coupling has two female ends (tapped) of the same size. Its shape makes it easy to screw on using an adjustable spanner.

Galvanized equal coupling characteristics and uses:

Although we use our fittings for decoration, this is a genuine plumbing part made of whiteheart malleable cast iron that complies with EN 10242 and ISO49 standards. Superior quality and a guarantee of rock-solid sturdiness!

The female (tapped) threads on this part are parallel gas threads (Rp, ISO 7-1 standard). They accept the tapered male threads (R, known as BSPT) of pipes and fittings of the same size.

• Screw-in depth, depending on the part screwed in and the tightening force:

  Size	Screw-in depth (approx.)
  1/4"	10 mm
  3/8"	10 mm
  1/2"	13 mm
  3/4"	15 mm
  1"	17 mm
  1"1/4	19 mm
  1"1/2	19 mm
  2"	24 mm
  2"1/2	27 mm
  3"	30 mm
  4"	36 mm

• Materials: galvanized cast iron
• Colour: galvanized (slightly shiny silver-grey)

Common assembly example:

Pipe 1 + Equal coupling + Pipe 2 = Total length of assembly

• 3/8'' = Pipe 1 + Pipe 2 + x cm
• 1/2'' = Pipe 1 + Pipe 2 + x cm
• 3/4'' = Pipe 1 + Pipe 2 + x cm
• 1'' = Pipe 1 + Pipe 2 + x cm
• 1''1/4 = Pipe 1 + Pipe 2 + x cm
