Isiflo Sprint is our new patented range of composite push-fittings combining the safety and strengh of a traditional mechanical fitting with the userfriendliness of a standard push-fitting. The installation of Isiflo Sprint happens in one simple move, requires no tools and no complicated preparation of the pipe. Just cut the pipe scarely and insert, with a slight twist, into the fitting. The result is a strong, firm and long-lasting connection between the pipe and the coupling.

 

  

Applications:
Isiflo Sprint fittings gives a tight and firm end-load resistant connection. To be used on the following pipes:
· PE, PEL, PEH, (PE 50, PE 80, PE 100) 
· PEX when using support

Important:
Insert shall be used on thin-walled PE pipes (for example SDR 17,6, on geothermal heat pumps etc.)

Materials:
Body: Composit, Glass reinforced Polyamide
Clamp ring: POM
Pushback ring: POM
O-ring: EPDM

100% Corrosion-resistant

Area of applications
· Cold water up to 40°C

- PE, PEL, PEH (PE 50, PE 80, PE 100)
- PEX when using support insert

Working pressure:
· Water - up to 16 bar
· Burst pressure - pipe burst before coupling

Tests and approvals:

Isiflo Sprint is approved for seawater.

Function description:
There is no need to chamfer the pipe-end before installation. The design of the new fitting ensures that the pipe enters the fitting easily, avoiding the need for a high push-in force. As the pipe enters the fitting, the push-back ring moves in the opposite direction, compressing the o-ring as the clamp ring grips the pipe. This ensures a leak tight connection - even under low pressure conditions. The same happens when you tighten the nut in an ordinary mechanical fitting. The main difference is that everything happens in one move, without the need for tools.

Installation procedure:

1. Cut the pipe as squarely as possible, checking that it is clean and free from damage.

2. Mark the installation depth on the pipe. The correct depth is indicated on each fitting.

3. Insert the pipe into the fitting with a slight twist. The twisting action reduces the installation force required to make the joint. No tools required.

PS: The pipe is fully inserted when the installation mark lines up with the edge of the fitting.

 

Dismantling and reuse:

Open the sleeve with a proper tool, like a pipe wrench. Pull the pipe out of the fitting. Thereafter remove the grip ring, o-ring and sleeve from the pipe.

The following components must be replaced if the fitting is to be reused:

- Sleeve

- Grip ring

- O-ring

Make sure that the push back ring is in place. The new components have to be assembled in the following order:

- O-ring

- Grip ring

- Sleeve

Tighten the sleeve by hand, and thereafter use a pipe wrench to lock the position.
By reuse of Isiflo Sprint the blue sleeve, the grip ring and o-ring must be replaced.
