32 fl oz Clear Uni-Weld® 9300 Series Primer (Tech Only)
Product Overview
The standard specification for preparing PVC and CPVC joints to ensure a permanent, leak-free chemical weld.
Pool techs across the industry stock the Uni-Weld #9336S because it reliably handles the aggressive surface preparation required for high-pressure pool plumbing. This 32 fl. oz. clear primer (UPC 038753933622) is a Low-VOC formula that meets SCAQMD 1168/316A standards, ensuring a deep chemical weld on both PVC and CPVC materials without the unsightly staining associated with purple alternatives.
Benefits & What Makes It Different
NSF and Low-VOC Compliant
Meets SCAQMD 1168/316A and NSF standards, ensuring the chemical preparation is safe for potable water and high-pressure pool filtration systems.
Dual-Material Versatility
Formulated to work effectively on both PVC and CPVC, allowing technicians to carry one 32 fl. oz. bottle for standard plumbing and high-temp heater repairs.
Aggressive Surface Softening
The #9336S formula penetrates the pipe surface deeply to create a porous layer, which is essential for the solvent cement to fuse the two pieces into a single solid unit.
Product Details
Tetrahydrofuran, Methyl Ethyl Ketone, Cyclohexanone, Acetone
Apply a thin, even layer to both the pipe end and the fitting socket while surfaces are clean and dry.
Compatibility
- Schedule 40 PVC
- Schedule 80 PVC
- CPVC Pipe and Fittings
When To Use This
Pro Tip
To avoid 'primer runs' that look messy on an equipment pad, use a dauber that is half the diameter of the pipe you are working on and wipe the excess off the rim of the can before applying.
Common Questions & Instructions
Is clear primer acceptable for all pool plumbing inspections?
While the #9336S provides a superior bond, some local building codes require purple primer for visual inspection; always check local regulations before completing a new construction project.
How much coverage can I expect from a 32 fl. oz. bottle?
A 32 fl. oz. container typically provides enough primer for hundreds of 2-inch pipe joints, making it the preferred volume for professional technicians managing multiple service routes.
Does this primer expire if the container has been opened?
Solvent primers like the Uni-Weld 9300 series will eventually evaporate or thicken; if the liquid becomes gel-like or cloudy, it should be replaced to ensure proper surface penetration.
