PRESSERS AND COUPLINGS
The pressers and couplings are made by turning from highly resistant tubing,
to guarantee material uniformity and resistance to crushing without breaking,
with flared ends. They then undergo second baking to eliminate any resistance
of materials and finally they are protected by electrolytic galvanising to
ensure greater resistance to atmospheric agents. The pressers are also available
in copper and come in the following standard sizes: 9x6 – 8x6 – 8x8, including
in copper; The couplings come in the following sizes:8x22 – 8x25 – 8x30 –
9x25 – 9x30. The left hand threaded couplings come in packs of 2 in the following
sizes: 9x30 – 9x25
