Boshart FIN4740 Series PVC Transition Coupling, Glue x Insert

The Boshart FIN4740 Series PVC Transition Coupling is a rough-in fitting built to join a solvent-weld PVC pipe run directly to a barbed insert connection in a single component. This family is available in sizes from 3/4" through 1" (model options FIN474-007 and FIN474-010), so plumbers can match the coupling to the pipe run at hand while keeping the same glue-to-insert transition design across the line. One end of every size in the series is sized for a standard glue (solvent weld) joint into Schedule 40 PVC pipe, while the opposite end is an insert (barb) connection designed to accept flexible tubing secured with a clamp or crimp ring. This dual-connection design makes the FIN4740 Series a practical transition piece anywhere a rigid PVC branch needs to step down to flexible tubing, or vice versa, without cutting in a second coupling or adapter. As with other FIN4740 Series fittings, these couplings are intended to be installed behind the wall or under the floor as part of the rough-in supply or distribution run, not as a finished, visible fixture.

Key Features

  • Trade Size Range: Available from 3/4" to 1" on both the glue and insert ends, sized for standard PVC pipe and flexible tubing runs.
  • Glue (Solvent Weld) End: Accepts a standard PVC solvent-cement joint for a permanent connection into rigid PVC pipe.
  • Insert (Barb) End: Insert fitting designed for flexible tubing, secured with an appropriately sized clamp or crimp ring at installation.
  • Transition Design: Combines two different connection methods in one fitting, eliminating the need for a separate adapter when moving from rigid PVC to flexible tubing.
  • FIN4740 Series: Part of Boshart's FIN4740 line of PVC transition fittings used in rough-in plumbing distribution.
  • PVC Construction: Molded PVC body suited for cold and pressurized water distribution lines commonly run in PVC systems.

Boshart FIN474-007 – Frequently Asked Questions

1) What sizes does the Boshart FIN4740 glue x insert coupling come in?
Two sizes: 3/4 inch glue x 3/4 inch insert (FIN474-007) and 1 inch glue x 1 inch insert (FIN474-010). Both ends are the same trade size on each part, so there is no size step built into the fitting. If you need to change diameter as well as connection type, you'll have to pair it with a reducing bushing or a reducing coupling.
2) Can I glue one end of this coupling to Schedule 40 PVC and push poly pipe on the other?
That is exactly what the FIN4740 coupling is for. One end takes a standard solvent-cement joint into rigid Schedule 40 PVC pipe, the other is a barbed insert end that flexible tubing slides over and is held with a clamp or crimp ring. The clamp is not included, so order gear clamps or crimp rings in the matching 3/4 inch or 1 inch size with the fitting.
3) Should I use a glue x insert transition coupling or a threaded PVC adapter to go from PVC to poly pipe?
A glue x insert coupling makes the change in one component: solvent weld into the PVC, barb into the poly. The threaded route means two fittings (a male adapter plus an insert adapter) and two joints, plus tape or dope. Use the FIN4740 style where the transition is permanent and buried behind the wall or under the floor, which is where these are meant to go. Keep the threaded pair when you want to be able to break the joint later for service.
4) Is the Boshart FIN4740 transition coupling all PVC, or is the barb end nylon?
It's a molded PVC body throughout, glue end and insert end alike. That matters on cold water distribution runs where you want the same material family as the PVC pipe it cements into. PVC is not for hot water service.
5) Is this Boshart coupling suitable for a finished, exposed connection?
No. The FIN4740 couplings are rough-in fittings meant for supply and distribution runs behind the wall or under the floor, not a finished visible fixture connection. For an exposed stub-out at a fixture, use a trim-rated supply and escutcheon instead.
6) How much length does the FIN4740 coupling add to my run?
The fitting measures 1.500 inches in height overall, so it is a short body. Worth knowing when you are working in a tight joist bay or a stud cavity and need to figure the cut length of the PVC before the barb end picks up the flexible tubing.
7) Where is the Boshart FIN474 coupling made?
Country of origin is the USA. That is the detail institutional and government buyers ask about for domestic-content procurement requirements on plumbing material.
