Valterra

<h3>About Valterra: Four Decades of RV and Plumbing Expertise</h3><p>Since 1981, Valterra Products has been a cornerstone manufacturer for the RV, pool &amp; spa, and plumbing industries. Headquartered in Mission Hills, California, this privately held company has spent more than four decades engineering the components that RV owners, campground operators, and plumbing professionals depend on every day. What sets Valterra apart is its remarkable breadth — from freshwater supply systems to waste management solutions, the brand covers virtually every fluid-handling need an RV or recreational property might have.</p><h3>A Comprehensive RV Parts Manufacturer</h3><p><strong>Valterra</strong> has earned a reputation as one of the most complete single-source suppliers in the RV aftermarket. Rather than specializing in a single niche, the brand engineers cohesive systems — meaning the fittings, hoses, valves, and supports in your rig are all designed to work together. This systems-level thinking reduces compatibility headaches and gives RV owners confidence that their components will perform reliably mile after mile.</p><p>At the heart of Valterra&apos;s lineup is an extensive range of <a href="/7632-valterra-plumbing-parts-accessories-200786">RV Plumbing Parts &amp; Accessories</a>. With over 40 products in this category alone, Valterra addresses everything from water fittings and freshwater hoses to tank hardware and holding system components. Whether you&apos;re winterizing a travel trailer or upgrading a Class A motorhome&apos;s water system, Valterra&apos;s plumbing catalog offers the depth and variety to get the job done right.</p><p>Managing black and gray water is one of the less glamorous — but absolutely critical — aspects of RV ownership. Valterra&apos;s RV Sewer Hose Supports are a prime example of the brand&apos;s practical engineering philosophy. Products like the EZ Slider and the Slunky series are designed to maintain a consistent downhill grade from your RV outlet to the dump station connection, preventing backups and mess. Sewer hose support systems come in multiple configurations to suit different campsite layouts and hose lengths.</p><p>Comfort inside the RV matters just as much as what&apos;s happening outside. Valterra&apos;s <a href="/7632-valterra-hotcold-water-mixer-faucets-200541">Hot/Cold Water Mixer Faucets</a> bring reliable temperature-blending performance to RV kitchens and bathrooms. Built to handle the space constraints and vibration demands unique to mobile living, these faucets are a natural complement to Valterra&apos;s broader plumbing ecosystem.</p><p>Safety on the road is another area where Valterra delivers. The brand&apos;s <a href="/7632-valterra-tire-pressure-monitoring-system-kit-55374">Tire Pressure Monitoring System Kits</a> give RV drivers real-time visibility into tire conditions — a critical consideration for large, heavy vehicles where a blowout can be both dangerous and costly. Proper tire pressure management is especially important for motorhomes and fifth wheels that may go extended periods between inspections.</p><h3>Why Choose Valterra?</h3><ul style="list-style:disc"><li><strong>Industry tenure:</strong> More than 40 years of focused manufacturing in the RV and plumbing sectors.</li><li><strong>Product breadth:</strong> Over 1,500 products spanning sewer systems, freshwater plumbing, faucets, safety accessories, and beyond.</li><li><strong>Systems approach:</strong> Components engineered to work together for simpler installation and greater reliability.</li><li><strong>Proven in the field:</strong> Trusted by OEM coach builders, aftermarket retailers, and DIY RV enthusiasts alike.</li></ul><p>Whether you&apos;re outfitting a new rig from scratch or replacing a worn component mid-trip, Valterra&apos;s catalog has the parts to keep your adventure rolling.</p>

Product Details

The Valterra RF855 is a double-barbed coupler fitting designed for connecting two 3/8-inch inner diameter hoses or tubing in RV plumbing, marine, and general fluid transfer applications. This plastic barbed fitting provides a secure, leak-resistant connection point for water lines, drain lines, and other low-pressure fluid systems.

Key Features:

  • Dual 3/8-inch barbed ends for connecting same-size hoses
  • Durable plastic construction resistant to corrosion
  • Ribbed barbs provide secure grip when used with hose clamps
  • Compact inline design for easy installation in tight spaces
  • Ideal for RV, marine, and general plumbing repairs and installations

This straight coupler is perfect for extending hose runs, repairing damaged sections, or creating custom plumbing configurations. The barbed design works with flexible tubing and should be secured with appropriate hose clamps for a watertight seal.
