Product Overview
Insert coupling joining 2 inch to 1.5 inch vacuum hose. Barbed at both ends, so the cuffs already fitted to each hose slip over it.
Important — This Is Not a Mender
A PVC connector does not join two bare hose ends. The barbs are there for hose cuffs to slide over, so each hose needs a cuff fitted before this part is any use.
A PVC join is four parts: two hoses, two cuffs, one connector. If you want to join two bare hose ends directly, you want a mender instead — Hose Mender 1.5 Inch (AH50) or Hose Mender 2 Inch (AH49).
Cuff, Mender or Connector — Which Do You Need?
Three different parts, routinely bought in error for one another.
| Part | Joins | How |
| Hose cuff | Hose to tool or wand | Threaded end onto the hose, slip end onto the tool |
| Hose mender | Hose to hose | Threaded both ends — screws straight onto two bare hose ends |
| PVC connector | Cuff to cuff | Barbed both ends — the cuffs already fitted to each hose slip over it |
The one that catches people out is the PVC connector. It does not join two bare hose ends. It needs a cuff already fitted to each hose, and the barbs are there for those cuffs to slide over. So a PVC join is four parts — two hoses, two cuffs, one connector. A mender is two hoses and one mender, and nothing else.
Temperature — Worth Knowing on a Truckmount
These are Spears PVC insert couplings. Spears publishes a maximum PVC service temperature of 60 degrees C (140 F).
For comparison, high-heat truckmount vacuum hose is rated to around 115 degrees C (240 F) at the truck. So the connector is the lower-rated component in that assembly.
Two honest qualifications. Spears' figure is stated for pressure-pipe service, and a vacuum line is not a pressure line — the failure mode would be softening and collapse rather than bursting. And waste air at the tool end of a long run is well below solution temperature at the truck.
The practical advice: PVC connectors suit portables and the cooler tool end of a run. Close to a truckmount waste outlet, a threaded mender or a cuffed joint is the safer choice.

Frequently Asked Questions
Can I join two bare hoses with this?
No. Each hose needs a cuff fitted first. Use a mender if you want to join bare ends.
Which cuffs do I need with it?
Standard screw cuffs sized to your hose — see Hose Cuff 1.5 Inch (AH42), Hose Cuff 2 Inch (AH44) and Hose Cuff 2.5 Inch (AH220).
Can I use it near the truckmount?
We would not. PVC is rated to 60 degrees C and the hose near the truck runs much hotter. Use it at the tool end or on portables.
Is it the same as the 1.5 inch version?
No — that is PVC Connector 1.5 Inch (AH74). Match the connector to your hose sizes.

What We See in the Field
A connector that's undersized, cracked or only half-seated becomes an air leak and costs recovery all the way back at the tool. On dual-hose and reducer setups, keep the run as smooth as practical — abrupt restrictions and unnecessary joins add up.
