System Sensor P-COUPLING — pack of 15 CPVC socket-to-socket couplings for FAAST aspiration sampling pipe.
A FAAST aspirating smoke detector draws air to its sensing chamber through a network of 3/4 in. CPVC pipe laid out in PipeIQ design software. The P-COUPLING is the plain in-line joiner that splices two straight lengths of that pipe where a run exceeds stock length or a damaged section is cut out. It is a solvent-weld fitting, not pipe, and it is catalogued only as a carton.
- Carton quantity: 15 couplings
- 3/4 in. nominal Schedule 40 CPVC, socket × socket
- Rated for continuous service at 175 psi (1,270 kPa) at 150°F (65°C)
- Post-chlorinated PVC made with BlazeMaster resin, matching the orange P-PIPE-210 pipe
- About 0.06 lb per fitting
Check the carton count, because it differs across the family: P-ELB-45 is 10, P-ELB-90 is 20, P-TEE is 15, P-ENDCAP is 25, P-UNION is 10. Use P-UNION where the joint must come apart again, since a coupling is a permanent solvent weld. P-PIPE-210 is the pipe itself, 14 lengths of 15 ft.
