High-Performance Cable Gland & Industrial Sealing Showcase
Precision-machined cable glands, venting valves, and heavy-duty connectors certified to UL, CE, and IP68 standards. Manufactured in Yueqing, Zhejiang, with full material traceability and micron-level thread accuracy.
The Global Strategic Status of PG 13.5 Cable Glands in Modern Industry
An analytical assessment of the enduring viability, engineering significance, and global supply chain integration of the DIN 40430 PG 13.5 standard within high-reliability mechanical, electrical, and automation ecosystems.
Information Gain & Sourcing Insight: Many procurement teams mistakenly replace PG 13.5 enclosures with M20×1.5 adapters, creating unnecessary leak paths and galvanic interfaces. Sourcing directly from an integrated Chinese manufacturer with precision tooling for DIN 40430 standards eliminates assembly bottlenecks, preserves ingress ratings, and guarantees mechanical tensile strength meeting Type 4X and IP68 criteria.

Frequently Asked Questions: PG 13.5 Engineering Specifications
Authoritative, field-tested answers addressing torque limits, thread conversions, IP testing parameters, and compliance standards for electrical engineering consultants and procurement teams.
What are the precise thread dimensions and pitch of a PG 13.5 cable gland?
Under the historic DIN 40430 standard, a Pg 13.5 thread features a major outer diameter (OD) of 20.4 mm (0.803 inches) and a pitch of 1.411 mm (corresponding to 18 threads per inch). The flank angle is 80 degrees, contrasting sharply with the 60-degree flank angle characteristic of ISO metric or NPT threads. The nominal chassis clearance hole recommended for a PG 13.5 clearance entry is 20.5 mm to 20.8 mm.
Can a PG 13.5 cable gland be directly threaded into an M20×1.5 metric port?
No. Although the nominal outer diameter of PG 13.5 (20.4 mm) appears deceptively close to M20 (20.0 mm), the thread profiles are fundamentally incompatible. PG 13.5 has an 80° flank angle with an 18 TPI pitch (~1.41 mm), while metric has a 60° flank angle and a 1.50 mm pitch. Forcing a PG 13.5 gland into an M20 tapped hole will strip threads and compromise IP68 ratings. Always use an engineered brass adapter (e.g., Male M20 to Female PG 13.5) or specify correctly tapped entry holes.
What is the standard clamping range for a PG 13.5 cable gland?
Standard HOONSUN PG 13.5 cable glands typically accommodate cable sheath diameters between 6.0 mm and 12.0 mm. For smaller signal leads, reduced-seal inserts allow clamping down to 4.0 mm to 8.0 mm. For maximum sealing integrity, select a gland configuration where your measured cable outer diameter sits in the middle 60% of the gland's rated clamping span.
What tightening torque should be applied to PG 13.5 cap nuts and bodies?
Tightening torque depends upon the structural material. For Nickel-Plated Brass and Stainless Steel PG 13.5 bodies, tighten the body into the enclosure tap at 5.0 to 6.25 Nm, and the cap nut around the cable at 4.5 to 5.5 Nm. For Nylon PA66 units, apply 3.0 to 4.0 Nm for the body locknut and 2.5 to 3.5 Nm for the dome nut. Over-torquing can deform the internal elastomeric insert, whereas under-torquing risks failing pull-out and immersion limits.
How does an IP68 rating differ from IP69K on industrial cable entries?
IP68 under IEC 60529 specifies protection against long-term hydrostatic submersion under defined pressure and duration (HOONSUN standard: 5 bar / 50 meters for 30 minutes up to 10 bar continuous). IP69K under DIN 40050-9 / ISO 20653 tests against high-pressure, high-temperature washdowns (80–100 bar water jet at 80°C from multiple angles). HOONSUN stainless steel PG 13.5 glands with vulcanized Viton seals achieve dual IP68/IP69K compliance.
Why is nickel plating critical on brass cable glands?
Unfinished bare brass rapidly forms copper carbonate verdigris when exposed to airborne moisture, sulfur dioxide, or saline maritime mists, causing binding of threaded nuts and seal degradation. Applying a uniform 5–8 micron electrolytic nickel electroplate passivates the alloy surface, lowers the friction coefficient for smoother torque transfer, prevents galvanic corrosion against aluminum panel walls, and provides an easy-to-clean sanitary exterior.
Can HOONSUN provide custom thread lengths and private branding for OEM accounts?
Yes. As an authentic primary manufacturer with over two decades of in-house CNC lathe and mould tooling capabilities, HOONSUN routinely machines custom spigot lengths (from compact 6 mm short threads up to 20 mm extended threads for thick structural vessels), private labels hex flats with client part numbers, and delivers customized multi-hole or flat-cable rubber inserts.
What certifications and compliance documents accompany factory shipments?
Standard HOONSUN production lots are backed by complete quality dossiers: CE Declarations of Conformity, UL Certificate cards (Underwriters Laboratories file testing), RoHS 2.0 / REACH chemical safety test reports from independent bodies (SGS/TUV), mill test certificates (EN 10204 3.1) for brass and stainless steel alloy lots, and IP68 water immersion test verification reports.
