1. Confirm Your Valve Model and Size
Before you click “add to cart,” you must verify that this kit matches your specific valve. The C113444 diaphragm repair kit is specifically engineered for 1″ pulse jet valves. It is most commonly compatible with the ASCO/Emerson SCG353A044, G353A044, and G353A053 series .
Why Compatibility Matters
Installing the wrong kit can cause the valve to stick open or fail to seal. Check the nameplate on your valve body. If it reads “353A044″ or similar, you are on the right track. If you have a ¾” valve, you will likely need the C113443 kit instead .
2. Understand What’s Inside the Kit
Knowing the components helps you assess quality and value. A standard C113444 repair kit typically includes the critical wear parts that degrade over time in a dust collector environment.
- The Diaphragm: This is the heart of the kit. It is usually made from NBR (Nitrile) orTPU (Thermoplastic Polyurethane) for flexibility and oil resistance. For high-temperature applications, look for Viton (FKM) construction .
- The Metal Plate: The center plate, often made of SS304 stainless steel, provides rigidity and prevents the diaphragm from distorting under pressure .
- The Spring and Seal: The kit includes the return spring and sometimes small pilot seals necessary to restore the valve to factory specs .

3. Choose Between OEM and Aftermarket Suppliers
You generally have two sourcing options: Original Equipment Manufacturer (OEM) or aftermarket manufacturers. Your choice often depends on budget and urgency.
Authorized Distributors (OEM)
Buying genuine Emerson/Asco kits guarantees a perfect fit and material specification. Distributors like Kempston Controls offer verified stock, which is crucial for critical applications where failure is not an option . However, OEM parts often come with a higher price tag and potential shipping delays if not locally stocked.
Aftermarket Manufacturers
Many factories, particularly in industrial hubs like Ningbo, China, manufacture compatible C113444 repair kits . These kits can cost significantly less (sometimes under $10 per unit, depending on volume) .
- Pros: Cost-effective, often available in bulk.
- Cons: Quality varies. Look for suppliers with audited status and certifications like SGS/BV, and inquire about the material (NBR vs. Viton) .
4. Verify Operating Conditions (Temperature & Pressure)
Not all diaphragms are created equal. You must ensure the materials in the repair kit suit your environment.
- Standard Conditions: If your system runs at typical temperatures (-20°C to +80°C) with standard compressed air, standard NBR or TPE diaphragms will suffice .
- High-Temperature Environments: For applications involving high temperatures or aggressive media, you need a kit with FPM/FKM (Viton) seals and diaphragms to prevent hardening and cracking .
5. Source from Reputable Sellers
To avoid counterfeit or substandard parts, check the seller’s credibility.
- Check Stock Status: If you need the part immediately, verify if the item is “In Stock” or if it is a “Back Order” item to avoid unexpected delays .
- Review Product Listings: On platforms like Amazon or specialized industrial sites, read the product details carefully. Some kits are listed for C113444 but specifically fit only the 1″ version, while others are combo packs .
- Request Specifications: Don’t hesitate to message suppliers (especially on global sourcing sites) to ask for material certifications or dimensional drawings .
Conclusion: Make the Right Purchase for Long-Term Savings
Buying the correct C113444 Diaphragm Repair Kit comes down to three things: verifying your valve model, choosing the right material for your environment, and sourcing from a trusted supplier. Whether you opt for a genuine OEM kit for guaranteed reliability or a cost-effective aftermarket alternative for routine maintenance, prioritizing quality will extend the life of your dust collector valves and maintain system pressure.
