Sold either as part of the flush sampling kit (ABS019F) or individually, it is used when sampling is required through a ceiling tile. It is the perfect solution when differing hole sizes are required in the same pipe run. The head features a standard 10mm central hole, into which can be inserted a choice of 8 jets with different sizes of sampling hole including: 2.0/2.5/3.0/3.5/4.0/4.5/5.0/5.5/6.0mm The required size jet is simply twisted off the strip and push fit into the head (no cement required)
PPGHT2 – 25mm – FLUSH HEAD WITH JETS
A 15mm hole is required in the ceiling tile, the head is then secured to the ceiling with the nut/washer (supplied) or with 2x6mm screws (not supplied). The 10mm connecting nylon tubing is then pushed into the sampling head from the rear. The locating for the tubing is concentric, therefore pushing the tubing firmly home ensures a secure and airtight fit. Do not paint, Only install with Bisson pipe, Do not obstruct the sampling holes.
