Description
The Spears® 1402-130 is the 1 in. PVC reducing tee that branches a flexible polyethylene irrigation mainline into a 1/2 in. female-NPT-threaded port without an extra reducer bushing or fitting stack. Two 1 in. barbed insert run ends, one 1/2 in. female NPT branch end. Molded dark-grey UV-stable PVC, Spears USA marking, domestic-manufactured to ASTM D2466.
Why You'd Reach for the 1402-130
- Three jobs in one fitting — tees the run into a 90° branch AND reduces the branch from the 1 in. run size down to a 1/2 in. threaded port AND transitions from flex poly to threaded; no separate insert tee + reducer bushing + male adapter stack
- Two barbed insert run ends — push 1 in. flexible polyethylene tubing onto each run port and cinch with a stainless hose clamp; no thread tape, no solvent cement on the mainline side
- Female NPT branch end — receives a 1/2 in. male-threaded fitting (sprinkler head riser, brass nipple, threaded valve outlet, drip manifold inlet, pop-up adapter)
- Dark-grey UV-stable PVC — molded for outdoor / surface-exposed irrigation lines; doesn't require burial like white SCH 40 PVC pipe fittings
- NSF-certified domestic manufacture — carries the “NSF-pw” mark for potable-water service, made in the U.S.A.
- Manufactured per ASTM D2466 — the controlling spec for PVC pressure pipe fittings
- Spears USA, domestic manufacture — computer-stress-analyzed mold design with reinforced material at the branch junction and the thread base
Where It Fits in the System
- Sprinkler-head risers off a poly mainline (the classic use): Run 1 in. flex poly underground in a straight line, drop a 1402-130 inline anywhere a head is needed, then thread a 1/2 in. male-NPT pop-up riser or nipple into the branch. Keeps the poly mainline straight and drops heads only where you want them.
- Drip irrigation submains: branch a drip submain off a 1 in. poly mainline into a 1/2 in. threaded port that feeds a pressure regulator, filter assembly, or distribution manifold.
- Equipment port drops: tap a 1 in. poly supply line for a 1/2 in. female NPT pickup feeding a filter housing inlet, pressure tank port, hose bib, or small valve.
- Manifold branching: when a 1 in. poly manifold feeds multiple 1/2 in. threaded outlets, chain 1402-130 tees inline rather than stacking insert tees + reducer adapters.
Specifications

Installation Notes
Both run ends are barbed inserts — same procedure on each: Cut the poly square. Warm the poly tubing in hot water for 30 seconds if it's a cold-day install (makes the insert push-fit easier). Push the barb fully into the poly so the pipe is seated past the last retention rib. Secure with a stainless steel hose clamp or pinch clamp positioned over the barbed section — tighten until the clamp screw is snug but not over-deformed.
Female NPT branch end: 2 to 3 wraps of PTFE thread tape (or pipe dope) on the MALE fitting that threads into the 1402-130's female port. Hand-tighten plus 1 to 2 turns with a strap wrench. DO NOT over-tighten. PVC female threads can split if you crank a male fitting too hard. If the joint leaks at proper torque, replace the tape and try again — don't keep tightening. Over-tightening is the #1 cause of cracked PVC female-thread ports in the field.
Plan branch direction before clamping the run: the branch port can be rotated to any angle around the run centerline before either run clamp is tightened. Mark the orientation while dry-fitting, then clamp.
All three ends need either a clamp or a tape-and-thread joint — un-clamped barbs creep loose under temperature cycling and irrigation surge; thread joints sealed with no tape weep at the start of every irrigation cycle.
