Slip Hub Flange 3" Thermoplastic, Black - Valterra T1005 The Valterra T1005 3" slip hub flange is a compact, universal-fit connection component designed for sealing and anchoring the terminus of 3" PVC or ABS drain lines in recreational vehicles, marine sanitation systems, and portable wastewater setups. Featuring a smooth black thermoplastic body with a 3" slip hub (ID 3.500", OD 3.950"), it accepts standard 3" pipe for solvent or adhesive bonding and provides a flat mounting surface for secure attachment to tank walls, hulls, or access panels using mechanical fasteners. Its low-profile design (0.31 in thick) and lightweight construction (0.27 lb) make it ideal for space-constrained installations where leak-proof integrity and easy service access are essential. Features - 3" slip hub (smooth bore) for direct insertion and bonding of 3" PVC/ABS pipe - Flat flange face enables secure mechanical mounting to tanks, bulkheads, or access doors - Universal fit design compatible with RV gray/black water tanks, marine holding tanks, and composting toilet outlets - Smooth exterior finish resists dirt buildup and simplifies cleaning - Lightweight thermoplastic construction withstands vibration, flexing, and temperature cycling - Molded with consistent wall thickness for reliable solvent or adhesive bonding - I.D. 3.500" / O.D. 3.950" ensures proper fit with standard 3" Sch 40 DWV pipe - Resistant to wastewater chemicals, odor permeation, and UV degradation (short-term exposure) - No threads or gaskets required?seal achieved via pipe cement and perimeter fastening - Easily integrated into DIY or OEM sanitation system builds Specifications - Brand Name: Valterra - Model Name: Valterra T1005 - Part Number: T1005 - Product Type: Flange - Connector Type: Slip Hub Flange - Hub Size: 3 in - Inner Diameter: 3.500 in - Outer Diameter: 3.950 in - Material: Thermoplastic (PVC-compatible) - Color: Black - Finish: Smooth - Product Dimensions: 0.62 x 0.62 x 0.31 in - Item Weight: 0.27 lb (122 g) - Number of Items: 1 - Country of Origin: Mexico - Global Trade Identification Number: Not applicable - Manufacturer: Valterra Products LLC Product Application This flange is used by RV technicians, boat builders, and off-grid system fabricators to create permanent, serviceable terminations for 3" waste lines exiting holding tanks, composting toilets, or gray water reservoirs. Installed by bonding pipe into the slip hub and screwing the flange face to a tank wall or access panel, it forms a watertight, vibration-resistant seal?critical in mobile environments where flexing and road shock can compromise joints. Commonly deployed in fifth wheels, travel trailers, sailboats, and tiny homes, the T1005 supports reliable, odor-free waste containment and simplifies future maintenance by providing a clean, flat surface for cap or valve attachment. Its compact size and chemical resistance make it a trusted component in modular sanitation systems where space, weight, and durability are paramount.
