90 Degree Elbow, FPT x FPT PVC Schedule 80 1" (808-010)

This 1" Schedule 80 PVC FPT × FPT 90 Degree Elbow provides an all-threaded right-angle directional change in a fully threaded Schedule 80 PVC pressure piping system. Both female NPT threaded ends receive standard 1" male-threaded pipe, nipples, or MPT fittings, routing the threaded run through a 90° turn without solvent cement, primer, or cure time at the elbow position.

Two parallel distinctions define where the 808-010 belongs in a system layout. The first is connection type. Within the Schedule 80 90° elbow family at 1", the all-socket 806-series elbow serves solvent-welded PVC pipe systems where both sides of the turn are cemented pipe ends; the mixed 807-series elbow bridges a solvent-welded inlet to a female-threaded outlet; and the 808-010 serves fully threaded assemblies where both sides of the turn are threaded — receiving nipples, MPT-terminated fittings, or male-threaded pipe ends on each side of the right-angle body. When both connections at the directional change point are threaded, the 808-010 is the correct elbow selection.

The second distinction is turn angle. At 90°, the 808-010 produces a right-angle turn — the standard directional change for routing pipe runs around corners, through wall penetrations, and between vertical and horizontal orientations. This distinguishes it from the 819-series FPT × FPT 45° elbow, which provides a shallower half-right-angle offset for diagonal routing, compound-angle assemblies, and reduced-turbulence directional changes. The 90° geometry is the more common selection for straightforward right-angle routing requirements; the 45° applies where the layout geometry demands a shallower turn or where two elbows must work together to create a custom offset. When the routing requirement is a clean right-angle direction change in a threaded system, the 808-010 is the direct solution.

The all-threaded FPT × FPT configuration serves several practical system contexts at 1". In fully threaded Schedule 80 assemblies — mechanical rooms, chemical process connections, equipment supply runs, and instrument distribution systems built with threaded pipe and nipples rather than solvent-welded PVC — the 808-010 is the standard right-angle elbow that routes the threaded run through 90° at every corner and directional change point. In hybrid systems where solvent-welded PVC mains transition to threaded branch sub-assemblies at equipment connections, the 808-010 handles directional changes within the threaded branch portion. In retrofit situations where a direction change must be added to an existing threaded system without cutting solvent-cemented pipe, the 808-010 threads directly into the assembly between existing nipples.

At 1", the 808-010 occupies a particularly high-frequency position in threaded Schedule 80 installations. One-inch NPT is one of the most common sizes across standard commercial and industrial equipment ports, valve bodies, pump connections, and threaded fittings — and the 90° directional change is the most fundamental routing operation in any piping layout. The combination of these two factors makes the 1" FPT × FPT 90° elbow a routine stocking component in any threaded Schedule 80 installation or field service inventory.

Manufactured in dark gray Schedule 80 PVC, this elbow delivers the increased wall thickness and mechanical strength required in industrial, chemical, and commercial pressure piping where Schedule 40 ratings are insufficient. PVC's broad chemical resistance covers acids, bases, salts, chlorine, and most common process fluids, providing long service life in corrosive environments where metal elbows would corrode, scale, or seize on threads over time. NSF/ANSI 61 listing confirms suitability for potable water contact.

Rated to 450 psi at 73°F, this elbow handles standard to elevated pressure service across a wide range of fluid handling applications in threaded Schedule 80 systems. Apply PTFE tape or compatible pipe thread sealant to all male threads before engaging either FPT end. Hand-tighten plus one to two turns — do not over-torque PVC female threads, as excessive force risks cracking the elbow body at the thread root. When assembling a nipple-elbow-nipple run, make up both ends evenly and avoid applying torsional stress to one end while tightening the other. Ensure correct rotational alignment before final make-up — the 90° direction of the turn is set at assembly and cannot be adjusted after both joints are tightened. Apply published pressure derating factors for service temperatures above 73°F.
