VSJOCO
VSJOCO manufactures PPH butt weld pipe caps designed for hygienic fluid transportation systems across multiple industrial sectors. These pipe end seals integrate material-specific properties with precision manufacturing to address the unique challenges of food processing and related industries.
A PPH butt weld pipe cap is a pipe fitting used to permanently seal the end of a piping system. It creates a tight barrier that prevents fluid leakage, stops external contaminants from entering the pipeline, and protects pipe ends from physical damage during operation and maintenance. These caps can also serve as temporary plugs during system inspections or repairs.
Resists acids, alkalis, salts, and most organic solvents, reducing replacement frequency and minimizing production downtime
Operates reliably across a temperature range of -20°C to +110°C, accommodating both cold and hot fluid transportation
Meets food-grade and drinking water standards, eliminating compliance risks for manufacturing facilities
Delivers high impact and pressure resistance, extending the operational life of piping systems
Features low density, making installation faster and reducing labor costs by up to 40% compared to metal alternatives
Manufactured through a seamless one-piece injection molding process, these caps eliminate potential leak points associated with welded seams. This design prevents cross-contamination of food products and reduces the risk of costly production shutdowns caused by system failures.
All VSJOCO PPH pipe caps conform to FDA 21 CFR 177.1520, ISO 15493, and NSF 61 standards. This compliance ensures that facilities meet GMP requirements and pass regulatory audits without additional modifications to their piping systems.
Compatible with both heat fusion welding and flange connection methods, these caps can be installed using standard equipment without specialized training. The UV-stabilized formulation resists degradation from sunlight exposure, reducing annual maintenance requirements by approximately 60%.
PPH material withstands exposure to a broad range of chemicals commonly used in food processing, cleaning, and industrial applications. This resistance allows the same pipe cap to be used across multiple process lines, simplifying inventory management and reducing procurement costs.

Clean and square the pipe end to remove burrs and debris
Heat both the pipe end and cap to the specified temperature using a fusion welding tool
Align the components and join them without rotation
Allow the joint to cool naturally under pressure
Perform a pressure test before putting the system into operation
Do not exceed the rated temperature and pressure limits
Avoid sharp impacts that could cause cracking
Use UV-stabilized versions for outdoor applications
Conduct annual visual inspections of all pipe joints
Butt weld caps are joined by welding the outer edges, making them suitable for larger pipe sizes (DN50 and above) and higher pressure applications. Socket weld caps fit over the pipe end, providing easier installation for smaller diameters.
Yes, all VSJOCO PPH pipe caps comply with FDA 21 CFR 177.1520 regulations for food contact materials.
VSJOCO PPH pipe caps can operate continuously at temperatures up to 110°C, with intermittent exposure to slightly higher temperatures possible depending on pressure conditions.
Yes, we offer custom sizes, colors, and markings to meet specific project requirements. Contact our engineering team for details.
Under normal operating conditions and with proper maintenance, VSJOCO PPH pipe caps typically last 15-20 years in food processing environments.
VSJOCO brings 15+ years of expertise in manufacturing industrial pipe fittings for global markets. Every PPH pipe cap undergoes 100% pressure testing before shipment to ensure consistent performance. We maintain a comprehensive inventory of standard sizes to support fast lead times of 7-15 days for most orders. Our dedicated technical support team provides 24-hour response times to assist with installation, specification, and troubleshooting.
