Camlock PP Type DP Male End Cap 65mm

The Camlock PP Type DP Male End Cap (65mm / 2½") is a heavy-duty, quick-connect dust plug designed to seal the female end of a Camlock coupling. Manufactured from high-grade Polypropylene (PP), this "Type DP" plug provides a watertight and dust-proof closure, making it essential for protecting open valves and hoses in the agricultural and industrial sectors of the Heidelberg region.

Technical Specifications

• Type: DP (Dust Plug) - Male adapter end.
• Size: 65mm (2½ inches) nominal diameter.
• Material: Glass-coupled Polypropylene (Acid and Chemical resistant).
• Pressure Rating: Typically rated up to 6 Bar (90 PSI) at ambient temperature (Model dependent).
• Temperature Range: Effective from -10°C to +70°C.
• Coupling Standard: Built to MIL-C-27487 / A-A-59326A specifications.

Key Performance Features

• Corrosion Resistance: Unlike aluminum or stainless steel, the Polypropylene construction is completely immune to rust and highly resistant to most fertilizers, herbicides, and pool chemicals used in Gauteng.
• Precision Machining: The male adapter face is engineered to seat perfectly against the internal gasket of a female coupler (Type B, C, or D), ensuring a leak-proof seal during the Easter 2026 pumping season.
• Lightweight Durability: The glass-reinforced PP offers high impact resistance while remaining light enough to handle easily on long hose runs or overhead JoJo Tank inlets.
• Contamination Shield: Acts as a critical barrier against red Heidelberg dust, insects, and debris that could clog Pascali pumps or contaminate livestock water supplies.
• Safety Lanyard Hole: Most 65mm DP plugs feature an integrated lug or hole for attaching a safety chain or wire, preventing the cap from being lost when the line is active.

Professional Usage & Tips

• Compatibility Check: The 65mm (2½") size is specific. Ensure your female couplers are the same size; a 50mm or 80mm coupler will not lock onto this plug.
• UV Protection: While the PP is UV-stabilized, prolonged exposure to the intense Highveld sun can eventually degrade any plastic. Store hoses in the shade or under a Wildebees tarpaulin when not in use.
• Chemical Synergy: This plug is ideal for "Liquid Fertilizer" setups. Unlike metal fittings, the PP will not pit or corrode when in contact with nitrogen-based fertilizers or acidic water.
• Seal Inspection: Before locking the arms of the female coupler onto this DP plug, check that the internal rubber gasket (usually Nitrile or EPDM) is clean and free of red Gauteng grit to ensure a vacuum-tight seal.
• Winter Care: Polypropylene can become slightly more brittle in sub-zero temperatures. Handle with care during the frosty Winter 2026 mornings in Heidelberg to avoid impact damage.

Common Use Cases

• Agricultural: Sealing off suction hoses on water bowsers and fertilizer sprayers.
• Irrigation: Closing manifold outlets on Rain Jet or large-scale irrigation systems.
• Water Storage: Protecting the outlet valves of 5,000L and 10,000L JoJo Tanks.
• Chemical Transfer: Capping off lines used for decanting cleaning agents or industrial fluids.

Pro Tip: If you find the cam arms on your female coupler are difficult to close over the 65mm DP plug, apply a tiny amount of Shield Sheen Silicone or a food-grade lubricant to the male adapter rim. This reduces friction and ensures the arms lock securely. Keep a spare DP plug in your Wildebees utility crate; it's the cheapest way to prevent an expensive pump failure caused by a "clogged line" full of dust and debris.
