Dawn KwikRepair 4" x 4" PVC Repair Coupler - KRC429-040

The Dawn KwikRepair KRC429-040 is a 4" x 4" PVC repair coupler engineered for fast, in-line repairs and installations where space is limited. The sleeve design lets you slide the fitting onto the pipe, apply primer and solvent, and create a permanent solvent-welded connection without O-rings or thrust blocking.

• Simple in-line repair: Slides onto existing pipe so you can repair or replace a section without bending or flexing the pipeline.
• Permanent solvent-weld seal: Provides a reliable, O-ring-free connection when installed with primer and solvent—no staking or thrust blocking required.
• Working pressure & dimensions: KRC429-040 rated at 165 PSI (at 73°F). Collapsed length ~10", extended length ~14½", outside diameter ~5¼", nominal inside diameter 4". (See product data sheet for full specs.)
• Material & compatibility: Manufactured from Schedule 40 PVC and designed for use with Schedule 40 PVC pipe of matching nominal size.
• Tight-space solution: Ideal for irrigation, landscape, agricultural, and commercial PVC repairs where excavation or pipe flexing is impractical.
• Made in USA & proven design: Part of Dawn Industries' KwikRepair line—patented design intended to reduce labor and material costs for field repairs.
