In the 'PG Series', the special features of Tungum Alloy are combined, in a simple design, with the traditional and proven concept of silver soldering (brazing) to create, as standard, a range of tube fittings offering the user:
The 'PG Series' of Silver Solder Fittings is designed to prevent leaks and hence eliminate the costs and dangers arising from their presence.
High Strength
Examples of all fittings in the standard 'PG Series' range have been proof tested at 1380 Bar (20.000 psi). and found to be free from leaks or evidence of stress.
Corrosion Resistance
All 'PG Series' components are manufactured from the highest quality, corrosion resistant materials, and fully conform to the 'Fit and Forget' philosophy of all Tungum products.
'PG Series' fittings require no painting, or external treatment.
Flat Faced Nipples
Allow the easy withdrawal of valves for servicing, without imposing stress on, or movement in, adjacent pipework.
High Efficiency Elastomer Seals
Pressure assisted - ensure the ultimate in leak free performance with liquids or gases, from vacuum to 10,000 psi - year after year.
Wide Range of Configurations
Supplied with BSP, BSP Taper, NPT, or other thread variants, male or female, to suit the application.
Primarily designed to complement Tungum Alloy tubing, the 'PG Series' of fittings are of course equally appropriate for use with Admiralty Brass, Copper or Cupro-Nickel tubing.
Size Range
6mm to 50mm O/D Tube - Proof Tested at 1380 Bar (20,000 psi)
Simple, No Nonsense Assembly
- Tees, Elbows and Sleeves can be permanently jointed single component couplings.
- To assemble Breakaway fittings, simply tighten the nut finger tight (to bring the prelocated 'O' ring seal down onto its mating face).
- Whilst restraining the body of the fitting with one spanner, tighten up the nut with another for a vibration resisting, leak free seal, on liquids or gases.
- No special nut position has to be noted.
- Minimal torque is transmitted to the tube.
All Components Which Will Be Brazed Are Made from Tungum Alloy Which Uniquely Aids the Consistent Production of Quality Joints
The low aluminium content ensures there are no barrier oxides to work against the even deposit of silver solder.
The absence of lead eliminates any potential for post-braze porosity.
Tungum Alloy's tolerance of thermal shock virtually banishes cooling cracks.
Tungum Alloy resists the stress corrosion sometimes found in other high tensile brasses following exposure to flux.
Tungum Alloy is corrosion resisting in all common states of heat treatment.
'PG Series' fittings have the general approval of Lloyds Register of Shipping who agreed the manufacturing plan and witnessed the type testing.
