Fishmouth Adapters

FORMUFIT specialty PVC Fishmouth Adapters allow PVC pipe to connect directly perpendicular to another PVC pipe of the same size using fasteners or PVC cement without cutting the original pipe. A small hole in the fishmouth allows fasteners like screws to connect to the outside of the PVC pipe. Fishmouth fitting adapters can also act as a secondary means to prop up PVC pipe in projects or as a pipe rest as required in a PVC pipe project.

Available Sizes

FORMUFIT PVC Fishmouth Adapters are available to buy online in the 1" and 1-1/4" PVC Sizes and fit standard Schedule 40 PVC size pipe only. For sizing information, please see our PVC 101 page.

More on Fishmouth Adapters

◼️Basic Description
Fishmouth Adapters can attach a PVC pipe to the side of an existing perpendicular pipe at a 90-degree angle without cutting the existing pipe. Using them, Fishmouths function ideally for adding load-bearing support when weight is too much for a PVC structure. They can also act as reinforcement struts and assist when pipe deflection occurs in longer lengths, resolving issues with slackness or drooping.

◼️Use
Connect the perpendicular segment with a screw or other fasteners, such as a #10 machine or self-tapping wood or machine screw. Then, connect the Fishmouth internal socket to another PVC pipe with PVC cement, permanently securing it.

◼️Design
The fishmouth is named as it gives the appearance of a fish's mouth due to its design that encompasses the radius of a PVC pipe. The fishmouth is an external and internal connector, with the outer 'mouth' section containing the radius of the pipe, which is either secured with fasteners through the included hole or can be cemented in place after adequately aligning. The internal element of the fishmouth connects over the end of the second segment of PVC pipe, leaving a smooth flush connection. When completely assembled, the fishmouth gives a completely concealed appearance and hides the entire assembly for a clean, finished look.

◼️Engineered Materials
PVC Fishmouth Adapters are injection molded from premium furniture-grade PVC resins, which are infused with UV-resistant and sunlight-blocking compounds. This added UV protection makes these adapters far more durable than other fittings, helps protect against weathering, discoloration, shattering, and breakage, and provides decades of use.

◼️Fitment and Securing
Internal Fishmouth Adapters can only be used with Schedule 40 size PVC pipe do the requirement of the inner diameter of the PVC pipe. The perpendicular connection can be attached with a screw, or other fasteners, such as a #10 machine or self-tapping wood screw.
