Coil Lengths of Corrugated Stainless Steel Gas Flex

DESCRIPTION:

GFS CSST system is manufactured in accordance with EN 15266 and BS 7838 which specifies the requirements for material, design, manufacture, testing and marketing of stainless steel pliable corrugated gas tubing kits for buildings with a maximum operating pressure less than or equal to 0,75 bars and a nominal size range from DN 10 to DN 50.

GFS Flex Fittings Assembly

1. Using a pipe cutting tool, make the required cut in the valley of two corrugations to the GFS CSST, ensuring full circular rotations are made in the same direction.

2. Using a stripper/safe knife cut the yellow sleeve approximately 30mm from tubing end. The cut should be made in the valley of two corrugations taking care and ensuring the minimum amount of material is removed.

3. Apply slight pressure to the cutting tool between rotations to ensure that the tube is free from sharp edges, burrs and that a clean cut is achieved.

4. Push the GFS CSST firmly into the GFS fitting ensuring the tube is fully inserted, and has bottomed-out against the stop of the fitting body.

5. Once the GFS tube is fully inserted into the GFS Fitting, remove the yellow plastic transportation ring situated between the GFS Hex and compression nut.

6. Tighten the assembled joint by hand, then using two spanners ( one to hold the hex on the fitting, the other to tighten the nut) tighten to achieve a mechanically secure gas tight seal.

7. ensure all joints are mechanically sounds before conducting a pressure drop gas tightness test. Once satisfied the installation is gas tight, wrap any exposed CSS and nut with self-amalgamating tape. This is to prevent corrosion thread that may occur form the ingress of corrosive debris or cleaning product.

SPECIFICATIONS:

- It is advised that all installations are correctly supported and clipped

- Fittings are made from Dezincification-Resistant Brass (DZR) to EN12164. They are Nickel coated for added material protection and corrosion resistance.

- All fittings include a heat resistant Silicone Rubber, Olive and a Brass Compression Washer

- The flame retardant Silicone Rubber Sealing Ring, enables the fitting to pass the high temperature test A of BS EN 1775

- Multiple Connecting Fittings Available

- Each Fitting has a yellow plastic clip to prevent compression turns before inserting the CSST, this needs to be removed before installation.
