FIRE FIGHTING FITTINGS AND COUPLINGS

British Standard

Instantaneous BS 336 coupling is a non-symmetrical quick connection coupling

with a male and female part.

The two parts are connected by plugging together. They come in two versions:

with twist or double pull release device. In both cases one or two spring loaded

plungers located in the female part grip behind the lip of the male part.

The couplings provide a straightforward solution to connect many lengths of

hose together and can be easily disconnected by twisting or pulling the release

mechanism. Instantaneous couplings come with a 21⁄2” nominal male and female

size and are manufactured according to British standard.

The couplings are only employable for delivery operation while for suction

operation round the thread couplings (BSRT) are required.

GOST Standard

GOST are symmetrical couplings manufatured according to Russian standard

(GOST 28352-89), available in several sizes.

They are suitable for delivery and suction operations.

They can be connected by rotating the clamp fitting where two grooved lugs

match the two cams of the connecting coupling.

UNE Barcelona Standard

Barcelona are symmetrical couplings with three engaging lugs, available in several

different sizes. Manufactured according to Spanish Standard UNE 23400 and

suitable for delivery operation only.

When rotating one coupling inside the other, the lugs of one coupling engage

themselves in the corresponding lugs of the other coupling assuring the tightness

of the connection.

JIS Standard

Nakajima are rigid inter-lock type symmetrical couplings, manufactured according

to JIS F 7335, suitable for delivery and suction operations.

They can be connected by rotating the clamp fitting where two grooved lugs

match the two cams of the connecting coupling.
